Workaround - Pulling HANA Views description into SAP Data Services

[former_member188157]

There is one issue I come across when I was building interfaces for third party components from S/4 Hana. When we add a description of columns in views as labels they wouldn't get populated as descriptions in SAP Data Services. Refer below screenshots to understand the problem in more details.

 

Problem Replication Scenario:-

 

Below is the screen shot from HANA view.

 



 

 

Below is the screen shot from BODS

 



 

Some findings:-

 

When I Checked the view by consuming in SAP BO Webi report I was able to see the Labels there.



 

 

 

When we use Tables not views from S/4 HANA their labels will get populated as descriptions.

 



 

 

Resolution/Workaround/Solution:-

 

After working with the team and different hit and try of experts from HANA and Data Services I was able to come to know that to get a description from the views of HANA database we need to update the metadata of the view by executing SQL script example.

 

COMMENT ON COLUMN "_SYS_BIC"."acan.mdi.interface/MATERIAL_INTER_2".MANDT IS 'XXXXXX';

 

Instead of 'XXXXXXX' in the above SQL we can write the description we want to put for the column MANDT of MATERIAL_INTER_2 view. This way we have to write SQL for each column in view and then execute it.

After the successful execution of the scripts we need to reimport the view in SAP BO Data Services and finally, we will be able to see the description which was added as comment in the metadata fo views
