How could I solve error: Modification failed because corresponding data cannot be migrated?

[former_member233452]

Hello,

I would like to add some columns to an entity of a deployed MTA with database module on SAP HANA 1 SPS12.

I don't want to delete the database table where I add some columns. I changed the data.hdbcds file and put some new columns there. If I push or redeploy the MTA I get the following error:

12/12/17 12:38:24.766 PM [APP/47-0] OUT Error: com.sap.hana.di.cds: Modification failed because corresponding data cannot be migrated. Reason: [1340001] at "src/data/data.hdbcds" (873:8-18)

Then I tried to use a cds-extension, but this also failed with the same error.

How could I solve this error?

Thanks!

I also am encountering the same problem in Hana 2.0 SP 02.
