ABAP CDS on HANA-12

cds

Exposing CDS view as oData Service

 

 

 

Create a CDS view and we have the view type as ‘BASIC’ view

1

To publish this as oData, add the annotation as: @OData.publish: true

2


@AbapCatalog.sqlViewName: ‘ZFLIGHT_VW’
@AbapCatalog.compiler.compareFilter: true
@AccessControl.authorizationCheck: #NOT_REQUIRED
@EndUserText.label: ‘Flight View CDS’
@VDM.viewType: #BASIC
@OData.publish: true
define view Zflight_View
as select from sflight
{
key sflight.carrid,
key sflight.connid,
key sflight.fldate,
sflight.price,
sflight.currency,
sflight.planetype,
sflight.seatsmax,
sflight.seatsocc
}


Activate the view. Then a symbol would appear at the line: @OData.publish: true, whihc tells that a service ‘ZFLIGHT_VIEW_CDS’ created and we have to add this service on Tx- /IWFND/MAINT_SERVICE

3


Go to the Tx- /IWFND/MAINT_SERVICE, click on Add Service button

4

Provide the alias name, and the service name and hit enter key.

The created service will appear in the list. Select the service and click on Add Selected Service.

7

Select local object and continue.

The information appears.

In the hana studio, activate the the view and a new symbol appears at the line’@OData.publish: true’ . Put the cursor on the mark

10

Click on the link: OData-Service

Here is the service. Now change the url and put ‘$metadata’

To execute the view and get the details, change the url sap/opu/odata/sap/ZFLIGHT_VIEW_CDS/Zflight_View

It returns all the entries.
