Steps
Intro
Always replace #### with your initials or group number.
Step 1
Overview
The new RAP based InA service exposure enables the SAP Business Technology Platform ABAP Environment developers to develop analytical queries(based on ABAP-CDS analytical data models) and expose them via the InA (Information Access) service protocol. In this Tutorial you will create a complete Analytical Data Model for Booking data. This consists out of dimensions for Carrier, Customer, Connection and Agency data, as well as an interface CDS view for Booking data which acts as a data source for the cube and query.
These analytical queries can be further consumed in the SAP Analytics cloud to create analytical models, stories, multi-dimensional reports and more.
Step 2
Import templates for Analytical CDS views
As a first task you will start to import templates that you will use in this tutorial to create Analytical CDS views such as dimension views, cubes and queries.
The templates already contain certain annotations that are mandatory for the above mentioned analytical CDS views. If values such as the name of a property have to be added this can then simply be done by using code completion.
Click on the following link to display the file analytical_templates.xml. Templates↓
Right-click on the browser window and save the content as an xml-file called analytical_templates.xml.
- Open ADT. In the menu choose Window > Preferences.
- In the Templates dialogue choose Import.
- Select the XML file analytical_templates.xml that you have saved.
The Import-Dialog only allows to select files having the extension
.xml.When you have downloaded the file using a different file extension you have first to rename your file so that it gets the extension.xml.
- You will see that three new templates have been imported that you will use in the following tutorial.
Press Apply and Close
Step 3
Create the first dimension for Carrier
Dimensions views are links to various master data, which are later used in reporting as further attributes (according to which different aggregations can be made) and thus make up the versatility of our Analytical Model.
In the following you will create four dimension views for Carrier, Customers, Connections and Travel Agencies so that you can visualize our measures Number of bookings and Flight price in relation to these dimensions.
That means you will be able to create different charts that show how much money was spend for bookings for the connection Frankfurt–>New York compared to the connection Frankfurt–>Sydney or that show how much money was spend for flights with a certain airline.
You will start to create a dimension view that contains the different Airlines / Carriers. Since our model will contain two measures, namely Number of bookings and Flight Price you will be able to answer questions such as
- How much bookings are there per Carrier ? or
- How much money was spend for bookings for a certain Airline?
Open ADT and login to your ABAP System. If you do not have a package, create a new one.
Right-click your package and choose New > Other ABAP Repository Object.
new Choose Core Data Services > Data Definition and click Next.
new data definition Enter the following values
- Name:
ZRAP500_I_CARRIER_### - Description:
Dimension for Carrier - Referenced Object:
/dmo/carrier
and click Next.
By selecting a table or another CDS view as Referenced object the wizard will use this object as a data source for the new CDS view and it will automatically add all fields into the DDL source code and it will also create camel Case aliases if needed.
- Choose a transport request and click Next.
Do NOT press Finish, because otherwise the wizard will not provide us the option to choose a specific template but would choose the template that you have used the last time.
In the Templates dialogue choose the Define a View Entity for a Dimension and press Finish. The Define a View Entity for a Dimension template is one of the new data definition templates that you have imported in the last step. This template contains certain annotations which will be explained below that are mandatory for dimension views.
define view
Step 4
Edit dimension view
- Now you need to edit the dimension view. Here you can use code completion to add the values for the annotations
@ObjectModel.representativeKey
and
@ObjectModel.text.element
that are needed for our dimension view.
- Click on
representativeKey, delete the placeholderrepresentativKeyso that you get an empty string ’’ , press CTRL + Space and chooseCarrierId.
- Click on
textElement, delete the placeholder stringtextElement, press CTRL + Space and chooseName.
- Save and activate the dimension.
- Your final code should look like following:
ZRAP500_I_Carrier_####
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Dimension for Carrier'
@Metadata.ignorePropagatedAnnotations: true
@Analytics.dataCategory: #DIMENSION
@Analytics.internalName: #LOCAL
@ObjectModel.representativeKey: 'CarrierId'
define view entity ZRAP500_I_Carrier_####
as select from /dmo/carrier
{
@ObjectModel.text.element: ['Name']
key carrier_id as CarrierId,
name as Name,
currency_code as CurrencyCode
}Coding explained
| Code | Explanation |
|---|---|
| @Metadata.ignorePropagatedAnnotations: true | ignore annotations from tables and base views, because you want to completely control/override the annotations here. |
| @Analytics.dataCategory | you define this CDS view as a dimension. |
| @Analytics.internalName: #LOCAL | Create UUIDs. |
| @ObjectModel.representativeKey: ‘CarrierId’ | you define CarrierID as the representative key to be able to refer to it using @ObjectModel.foreignKey.association in the Cube that you will create later |
| @ObjectModel.text.element: [‘Name’] | Using this annotation you define that the attribute Name, contains the text element for a given CarrierId. |
Step 5
Create three additional dimensions
Customer Dimension
The data for customers is contained in the table /dmo/customer. So you have to follow all steps above and create a dimension ZRAP500_I_Customer_#### and use the table /DMO/customer as a data source / reference object.
The table /dmo/customer contains the columns first name and last name, but not the full name of the customer. You will hence add a new field to our CDS view where you calculate the full name so that you can use it as the text element for the key field CustomerId.
The table /dmo/customer also contains fields that are too long to be used in analytics scenarios and it contains administrative fields that you do not want to show. You will hence delete these fields from the field list after having used the Define a View Entity for a Dimension template.
- Right click on your Core Data Services folder, choose Data Definition > New > Data Definition. Enter following values and press Next:
- Name:
ZRAP500_I_Customer_#### - Description:
Dimension for Customer - Referenced Object:
/dmo/customer
- Select a transport request and press Next
- Select again the template Define a View Entity for Dimension and press Finish
- Add a new field
CustomerNamewhich will later be specified as the text element for the key field.
concat_with_space(first_name, last_name, 1) as CustomerName,
- Remove or comment out these fields because they are too long for our analytics scenarios and you do not need any administration fields.
Code
// email_address as EmailAddress,
// createdby as Createdby,
// createdat as Createdat,
// lastchangedby as Lastchangedby,
// lastchangedat as LastchangedatAdd the association
_Countryassociation [1] to I_Country as _Country on $projection.CountryCode = _Country.Countryand add
_Countryto the field list so that it is exposed.
Add new fields and an association Choose the property
CustomerIdfor the annotation @ObjectModel.representativeKey and choose the newly created propertyCustomerNamefor the annotation @ObjectModel.text.element.
Add text Element Save and activate the dimension.
You expose the association
_Countryto be able to access country information in the cube and query.
- Your final code should look like following:
ZRAP500_I_Customer_####
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Dimension for Customer'
@Metadata.ignorePropagatedAnnotations: true
@Analytics.dataCategory: #DIMENSION
@Analytics.internalName: #LOCAL
@ObjectModel.representativeKey: 'CustomerId'
define view entity ZRAP500_I_Customer_####
as select from /dmo/customer
association [1] to I_Country as _Country on $projection.CountryCode = _Country.Country
{
@ObjectModel.text.element: ['CustomerName']
key customer_id as CustomerId,
first_name as FirstName,
last_name as LastName,
concat_with_space(first_name, last_name, 1) as CustomerName,
title as Title,
street as Street,
postal_code as PostalCode,
city as City,
country_code as CountryCode,
phone_number as PhoneNumber,
// email_address as EmailAddress,
// createdby as Createdby,
// createdat as Createdat,
// lastchangedby as Lastchangedby,
// lastchangedat as Lastchangedat
_Country
}
```
***Connection Dimension***
The information about the connections (flights) is stored in the table `/dmo/connection`. In this dimension view you again add a new field. The newly created field **Trip** will show the departure airport and the destination airport in one string.
For tables such as `/dmo/connection` that contain more than one key field, the key fields that are not annotated as the representative key field have to be annotated with a foreign key relationship.
Since the key field `ConnectionId` will be annotated as the `representativeKey` you have to add an association that points to the Carrier dimension view which will be added as a foreign key relationship to the key field `CarrierId`.
1. Right click on the folder **Data Definitions** > **New** > **Data Definition**.
2. Enter the following values and press **Next**.
- **Name**: `ZRAP500_I_Connection_####`
- **Description**: `Dimension for Connections`
- **Referenced Object**: `/dmo/connection`
3. Select a transport request and press **Next**.
4. Select again the template **Define a View Entity for Dimension** and press **Finish**.
5. Add a new field **Trip** which will later be specified as the text element for the key field `ConnectionId`.
`concat(airport_from_id, concat(' -> ', airport_to_id)) as Trip, `
6. Add an association `_Carrier`
<pre></pre>
association [1] to ZRAP500_I_Carrier_#### as _Carrier on $projection.CarrierId = _Carrier.CarrierId
and expose it in the field list by adding `_Carrier`
7. Add the following annotation to the key field `CarrierId`
`@ObjectModel.foreignKey.association: '_Carrier' `
8. Select the field `ConnectionId` for the annotation `@ObjectModel.representativeKey`
9. Select the field `Trip` for the annotation `@ObjectModel.text.element`
10. Save and activate the dimension view.
11. Your final code should look like the following:
```ZRAP500_I_Connection_####
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Dimension for Connections'
@Metadata.ignorePropagatedAnnotations: true
@Analytics.dataCategory: #DIMENSION
@Analytics.internalName: #LOCAL
@ObjectModel.representativeKey: 'ConnectionId'
define view entity ZRAP500_I_CONNECTION_#### as select from /dmo/connection
association [1] to ZRAP500_I_Carrier_#### as _Carrier on $projection.CarrierId = _Carrier.CarrierId{
@ObjectModel.text.element: ['Trip']
@ObjectModel.foreignKey.association: '_Carrier'
key carrier_id as CarrierId,
key connection_id as ConnectionId,
airport_from_id as AirportFromId,
airport_to_id as AirportToId,
concat(airport_from_id, concat('->', airport_to_id)) as Trip,
departure_time as DepartureTime,
arrival_time as ArrivalTime,
distance as Distance,
distance_unit as DistanceUnit,
_Carrier
}
```
***Agencies Dimension***
The information about the Agencies that perform the bookings is stored in the table `/dmo/agencies`.
1. Right click on the folder **Data Definitions** > **New** > **Data Definition**.
2. Enter the following values and press **Next**
- **Name**: `ZRAP500_I_Agency_####`
- **Description**: `Dimension for Agencies`
- **Referenced Object**: `/dmo/agency`
3. Select a transport request and press **Next**
4. Select again the template **Define a View Entity for Dimension** and press **Finish**
5. Remove these fields because they are too long for our analytics scenarios
```
// email_address as EmailAddress,
// web_address as WebAddress
```
6. Choose the property **Name** for the annotation @ObjectModel.text.element.
<pre> @ObjectModel.text.element: ['Name'] </pre>
7. Choose the property `AgencyId` for the annotation @ObjectModel.representativeKey.
` @ObjectModel.representativeKey: 'AgencyId' `
8. Save and activate the dimension view.
9. Your final code should look like the following:
```ZRAP500_I_Agency_####
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Dimension for Agency'
@Metadata.ignorePropagatedAnnotations: true
@Analytics.dataCategory: #DIMENSION
@Analytics.internalName: #LOCAL
@ObjectModel.representativeKey: 'AgencyId'
define view entity ZRAP500_I_Agency_#### as select from /dmo/agency {
@ObjectModel.text.element: ['Name']
key agency_id as AgencyId,
name as Name,
street as Street,
postal_code as PostalCode,
city as City,
country_code as CountryCode,
phone_number as PhoneNumber
// ,
// email_address as EmailAddress,
// web_address as WebAddress
}
```
### Booking interface view
You now have to create an interface view that serves as a data source for the Cube.
1. Right click on the folder **Data Definitions** and choose **New** > **New Data Definition** from the context menu.
2. Enter the following values and press Next
- **Name**: `ZRAP500_I_Booking_####`
- **Description**: `Interface View for Booking`
- **Referenced Object**: `/dmo/I_Booking_U`
3. Select a transport request and press **Next**.
Do **NOT** press finish at this point because you need to select a different template in the next step.
4. This time select the template **Define a View Entity** and then press **Finish**
5. Add an annotation `@Semantics.amount.currencyCode` to the property **Flight Price** that points to the property `CurrencyCode`.
<pre> @Semantics.amount.currencyCode: 'CurrencyCode'</pre>
6. Add a new field `AgencyId`. The value for this field will be retrieved using the association `_Travel`.
That points to the parent entity. This way the field `AgencyId` can be used as a dimension field.
<pre> _Travel.AgencyID as AgencyID, </pre>
7. Save and activate the interface view.
8. Your final code should look like the following:
```ZRAP500_I_Booking_####
@AbapCatalog.viewEnhancementCategory: [#NONE]
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Interface View for Booking'
@Metadata.ignorePropagatedAnnotations: true
@ObjectModel.usageType:{
serviceQuality: #X,
sizeCategory: #S,
dataClass: #MIXED
}
define view entity ZRAP500_I_Booking_#### as select from /DMO/I_Booking_U {
key TravelID,
key BookingID,
BookingDate,
CustomerID,
AirlineID,
ConnectionID,
FlightDate,
@Semantics.amount.currencyCode: 'CurrencyCode'
FlightPrice,
CurrencyCode,
_Travel.AgencyID as AgencyID,
/* Associations */
_BookSupplement,
_Carrier,
_Connection,
_Customer,
_Travel
}
```
### Create cube
>The Cube is the analytical interface view that is ultimately used in the query and "holds together" the model. In addition to the facts and the measurable key figures (if necessary also calculations), it contains references to the dimensions.
You will now use the Booking interface view as a data source to create a cube. All cubes must have at least one measure. The measurable data are the quantifiable fields that can be calculated, such as number of flight bookings and price of a flight. Using a query, you can SUM these fields. To create a cube, there is a mandatory header annotation:
<pre>@Analytics.dataCategory: #CUBE </pre>
This annotation is part of the template **Define a View Entity for a Cube** that you have imported in your ADT installation at the beginning of this tutorial.
1. Right click **Data Definition** and choose **New** > **New Data Definition**.
2. Enter the following values and press **Next**
- **Name**: `ZRAP500_I_BookingCube_####`
- **Description**: `Booking Cube`
- **Referenced Object**: `ZRAP500_I_BOOKING_####` (The booking interface view)
3. Choose a transport request and then choose **Define a View Entity for a Cube** and click **Finish**.
4. Add the following associations
```associations
association [0..1] to ZRAP500_I_Customer_#### as _Customer on $projection.CustomerID = _Customer.CustomerId
association [0..1] to ZRAP500_I_Carrier_#### as _Carrier on $projection.AirlineID = _Carrier.CarrierId
association [0..1] to ZRAP500_I_Connection_#### as _Connection on $projection.AirlineID = _Connection.CarrierId
and $projection.ConnectionId = _Connection.ConnectionId
association [0..1] to ZRAP500_I_AGENCY_#### as _Agency on $projection.AgencyID = _Agency.AgencyId
```
you also need to add the following to entries to the field list
<pre></pre>
_Agency,
_Customer._Country as _CustomerCountry
5. In the created cube you define `foreignKey associatons` via `_Customer`, `_Carrier`, `_Connection`, and `_Agency` to be able to fetch and expose information in the cube and in the query.
- Add the annotation `@ObjectModel.foreignKey.association: '_Customer'` to the field `CustomerId`
- Add the annotation `@ObjectModel.foreignKey.association: '_Carrier'` to the field `AirlineID`
- Add the annotation `@ObjectModel.foreignKey.association: '_Connection'` to the field `ConnectionId`
- Add the annotation `@ObjectModel.foreignKey.association: '_Agency'` to the field `AgencyID`
6. Comment out both lines of annotation `@Semantics.amount.currencyCode` and the property **Flight Price**.
7. Add the following two fields alongside with a foreign key association
```foreignKey
@ObjectModel.foreignKey.association: '_CustomerCountry'
_Customer.CountryCode as CustomerCountry,
_Customer.City as CustomerCity,
```
8. You add fields that contain information about the customers
```customer
@ObjectModel.foreignKey.association: '_CustomerCountry'
_Customer.CountryCode as CustomerCountry,
_Customer.City as CustomerCity,
_Connection.Trip as Trip,
```
9. You now add Measures to our cube.
You add a field `TotalOfBookings`
```totalOfBooking
@EndUserText.label: 'Total of Bookings'
@Aggregation.default: #SUM
1 as TotalOfBookings,
```
and the field **Flight Price** which is annotated as follows
```Flight Price
@Semantics.amount.currencyCode: 'CurrencyCode'
@Aggregation.default: #MIN
FlightPrice,
```
10. Save and activate the cube.
11. Your final code should be look like following:
```ZRAP500_I_BookingCube_####
@AccessControl.authorizationCheck: #CHECK
@EndUserText.label: 'Booking Cube'
@Metadata.ignorePropagatedAnnotations: true
@Analytics.dataCategory: #CUBE
@Analytics.internalName: #LOCAL
define view entity ZRAP500_I_BookingCube_####
as select from ZRAP500_I_Booking_####
association [0..1] to ZRAP500_I_Customer_#### as _Customer on $projection.CustomerID = _Customer.CustomerId
association [0..1] to ZRAP500_I_Carrier_#### as _Carrier on $projection.AirlineID = _Carrier.CarrierId
association [0..1] to ZRAP500_I_Connection_#### as _Connection on $projection.AirlineID = _Connection.CarrierId
and $projection.ConnectionId = _Connection.ConnectionId
association [0..1] to ZRAP500_I_Agency_#### as _Agency on $projection.AgencyID = _Agency.AgencyId
{
key TravelID,
key BookingID,
BookingDate,
@ObjectModel.foreignKey.association: '_Customer'
CustomerID,
@ObjectModel.foreignKey.association: '_Carrier'
AirlineID,
@ObjectModel.foreignKey.association: '_Connection'
ConnectionID as ConnectionId,
FlightDate,
// @Semantics.amount.currencyCode: 'CurrencyCode'
// FlightPrice,
CurrencyCode,
@ObjectModel.foreignKey.association: '_Agency'
AgencyID,
@ObjectModel.foreignKey.association: '_CustomerCountry'
_Customer.CountryCode as CustomerCountry,
_Customer.City as CustomerCity,
_Connection.Trip as Trip,
/* Measures */
@EndUserText.label: 'Total of Bookings'
@Aggregation.default: #SUM
1 as TotalOfBookings,
@Semantics.amount.currencyCode: 'CurrencyCode'
@Aggregation.default: #SUM
FlightPrice,
/* Associations */
_Carrier,
_Connection,
_Customer,
_Travel,
_Agency,
_Customer._Country as _CustomerCountry
}
```
### Implement query as CDS view entity
Since a query belongs to the projection layer (formerly known as consumption layer) it must have a **C** in its name according to the naming convention used in the Virtual Data Model (VDM) used in SAP S/4HANA.
Again you can use a template that you have imported at the beginning of this tutorial.
1. Right click **Data Definition** and choose **New Data Definition**.
2. Enter the following values and press **Next**
- **Name**: `ZRAP500_C_BookingQuery_####`
- **Description**: `Query for Booking`
- **Referenced Object**: `ZRAP500_I_BookingCube_####`
3. Choose a transport request and then press **Next**.
4. In the following dialogue choose **Define a View Entity for Query** and click **Finish**.
5. Edit the code of your query with removing **KEY** from `TravelID` and `BookingID`, add the annotation **@AnalyticsDetails.query.axis** to all properties except the two measures `FlightPrice` and `TotalOfBookings`. All fields beside the field `CustomerCountry` get the annotation **@AnalyticsDetails.query.axis: #ROWS**, whereas the field `CustomerCountry` gets the annotation **@AnalyticsDetails.query.axis: #COLUMN**.
6. You add a currency conversion to the field `FlightPrice` to be able to comparison all flight prices in a single currency.
```
@Semantics.amount.currencyCode: 'CurrencyCode'
currency_conversion (
amount => FlightPrice,
source_currency => CurrencyCode,
target_currency => cast( 'EUR' as abap.cuky( 5 ) ) ,
exchange_rate_date => cast ('20200101' as abap.dats),
exchange_rate_type => 'M'
) as FlightPrice
```
7. Save and activate the query.
> With the annotation **@AnalyticsDetails.query.axis:<VALUE>**, the elements of the view can be positioned on multiple axes: Rows, Columns and Free. The elements can be directly annotated with their axis. All measures (elements which can be aggregated) need to be on the same axis. The annotation of the first measure will therefore be used for all measures of the query. If **@AnalyticsDetails.query.axis:<VALUE>** is not found, the system positions the measures on the columns.
8. Your final code should look like the following:
```ZRAP500_C_BOOKINGQUERY_####
@EndUserText.label: 'Flights Query'
@AccessControl.authorizationCheck: #NOT_ALLOWED
define transient view entity DEF23_Flights_Query
provider contract analytical_query
as projection on DEF23_Flights_Cube
{
@AnalyticsDetails.query.axis: #ROWS
TravelID,
@AnalyticsDetails.query.axis: #ROWS
BookingID,
@AnalyticsDetails.query.axis: #ROWS
BookingDate,
@AnalyticsDetails.query.axis: #ROWS
CustomerID,
@AnalyticsDetails.query.axis: #ROWS
AirlineID,
@AnalyticsDetails.query.axis: #ROWS
ConnectionId,
@AnalyticsDetails.query.axis: #ROWS
FlightDate,
@AnalyticsDetails.query.axis: #ROWS
CurrencyCode,
@AnalyticsDetails.query.axis: #ROWS
AgencyID,
@AnalyticsDetails.query.axis: #COLUMNS
CustomerCountry,
@AnalyticsDetails.query.axis: #ROWS
CustomerCity,
@AnalyticsDetails.query.axis: #ROWS
Trip,
TotalOfBookings,
@Semantics.amount.currencyCode: 'CurrencyCode'
currency_conversion (
amount => FlightPrice,
source_currency => CurrencyCode,
target_currency => cast( 'EUR' as abap.cuky( 5 ) ) ,
exchange_rate_date => cast ('20200101' as abap.dats),
exchange_rate_type => 'M'
) as FlightPrice
}
```
### Data preview
Similar to the SAP Fiori Elements preview which is offered for OData V2 UI and OData V4 UI service bindings there is now an Analytical Data Preview available. This can be used by the ABAP developer to test the implementation of an Analytical Query since the preview uses the InA protocol.
Now that you have created the query it is possible to use a data preview to test our implementation.
1. Navigate to the folder **Data Definition**
2. Right click on the query `ZRAP500_C_BOOKINGQUERY_####` and select **Open with** > **Data Preview**
3. A new browser tab will open and you might have to authenticate using the credentials of your SAP BTP ABAP environment system.
4. You can see the data that has been retrieved using the InA-Protocol. Please note that the measures are grouped by the **Country/Region Key**.
### Create service definition
You use a service definition to define which data is to be exposed as a business service, using one or more business service bindings.
1. Right-click your created query in step 6 and choose **New Service Definition**.
2. Enter the following values and press **Next**.
- **Name**: `ZRAP500_UI_BOOKING_####`

- check if Exposed Entity is your created query `ZRAP500_C_BOOKINGQUERY_####`
3. Select transport request and press **Next**.
4. Select the template **Define Service** and press **Finish**.
5. After the query is exposed as a service it must be activated by pressing **Ctrl+F3**
### Create InA UI service binding
The service binding is used to bind a service definition to a communication protocol and in our case, the protocol that enables web-based data access from ABAP systems is the Information Access (InA) protocol.
1. Right click your newly created service definition and choose New Service Binding.
2. Enter the following values and press **Next**
- **Name**: `ZRAP500_UI_BOOKING_####`
- **Description**: `Booking Query Service Binding`
- Choose **InA - UI** as **Binding Type**
- Check that in the field **Service Definition** the service definition `ZRAP500_UI_BOOKING_####` is listed that you have created service definition in last step
3. Choose a transport request and click **Finish**.
4. Activate your service binding.
5. After activation, the external service name for your query is displayed.
>The analytical query will be displayed with the external service name in SAP Analytics Cloud as the data source.
### Create IAM App
