Formula Aggregation not pushed down to HANA DB

Hi SAP Experts,

We are creating a query in Query Designer. The query contains a formula with exception aggregate on material. See attachment 1 for details.

When I execute and explain the query in RSRT, it runs for more than 1 min and the explain also says it has not been pushed down to HANA DB

In RSRT query properties, we've tried each 'Operation in BWA/HANA' parameters, but the result is same.

We are on BW7.4 SP7. HANA DB version is 1.00.70.00.386119

According to SAP document, formula exception aggregate should be pushed down to HANA DB.

Can any SAP expert advise if there's any specific setting you need to make to enable this? Thanks.

Regards,

Aaron
