Error when trying to delete from Data Store Entity

Appian will NEVER delete any structural data from DB and only add things. E.g. renaming a field in CDT will create a new field in DB and leave the old one.

Thank you Stefan Helzle I was not aware Appian does not change the Tables. That fixed my issue.

Go to your DB designer and drop the tables affected by your change.

No I did not! Can you point out how to accomplish that please?

After you modified the CDT, did you re-create the tables? Appian will not remove any constraints automatically.
