BW4HANA Migration - shell conversion - 0SRM_TD_PO has Key Fields but No Aggregation Flag Set

Hello Team,

I am working in a BW4HANA conversion project (shell conversion)

Transaction used: RSB4HCONV -> Execute check for specific scope

I added a data flow for a DSO

During execution of the tasks, i am getting the following error.

" 0SRM_TD_PO has Key Fields but No Aggregation Flag Set".

Any ideas?

Best Regards,
