Selective delta from ODS to CUBE

Hi all,

I want to set up a delta flow from an ODS to CUBE, but with some data selections in the delta init request.

However, the data selections are disabled for the export datasources of ODSs(debugging confirmed this).

Could somebody explain this behaviour to me? Also, could somebody let me know how I can set up selective delta from ODS to CUBE?

Thanks a lot.
