All about CDS Annotations

This blog would give insights about the Annotations used in the S4HANA CDS DDL views.

If you are begineer then you will be puzzeled what are the available Annotations which we can use while creating a CDS view. SAP doesn’t allow any customer specific annotations so you have to use what ever SAP delivered.

Below is the whole list available in English and sorted by Annotation group. Intentionally added in code format so that it would easy to copy 👍

Next question is how we to get this list. It’s pretty simple, every information in SAP stored in SAP tables itself 😊  in this case ABDOC_CDS_ANNOS

SELECT * FROM ABDOC_CDS_ANNOS where SPRAS = 'E'

You can check SAP help on these Annotations using the below link

https://help.sap.com/doc/saphelp_nw751abap/7.51.0/en-US/63/0ce9b386b84e80bfade96779fbaeec/content.htm?no_cache=true

 

Now I want to explain how to get the list of Annotations used in a given CDS view. Recently I saw few questions in SDN about how to CDS views where Odata extraction is enabled, What are all Query CDS views which are available etc…You can play with SQL for answering questions about CDS meta data.

There were two SAP delivered CDS views one for header information and one for the field information.

 

Header level Annotations of a CDS view 

//This is select statement
Select
 * from 
 CDSVIEWANNOPOS

//But I want see Annotations of one CDS view so I added where clause as shown below
Select
 * from 
 CDSVIEWANNOPOS 
 where cdsname = 'I_MATERIAL'

 

This is how I_MATERIAL CDS was defined.

 

This is the output of the select statement if we exexute the 2nd SQL shown above code sample

 

We can notice highlighted Annotations which doesn’t exist in the CDS , these are the Annotation groups related to the Annotations defined in the CDS.

 

So I had modified the SQL statement so that output shows only Annotations available in CDS

Select
 * from 
 CDSVIEWANNOPOS 
 where cdsname = 'I_MATERIAL'
 AND ANNOTATIONNAME LIKE '%.%'

 

 

Field level Annotation of a CDS view

select * from 
CDS_FIELD_ANNOTATION
WHERE CDSNAME = 'I_MATERIAL'
and  ANNOTATIONNAME LIKE '%.%'

 

 

Hope this blog will give kick start on the annotations.

Please leave your comments and suggetions so that I can add if anything missing or wrong.

 

Thanks,

Shanthi
