BAPI_SCHEDULE_MAINTAIN throws error for time- independent scheduling agreement

Hi All,

I get the below error while modifying a stock transport Scheduling agreement in UI5 using BAPI “BAPI_SCHEDULE_MAINTAIN”

“Scheduling agreements with time-independent conditions are not supported”

Found a note 1046794-

"BAPI_SAG_CHANGE (and BAPI_SAG_CREATE) can only treat scheduling agreements with time-dependent conditions. Document conditions are not supported. Therefore, this kind of scheduling agreements cannot be processed. This is a missing functionality”

To meet some finance requirements, we need to use time-independent conditions in the scheduling sgreement, in order for a custom condition type to be picked up.

I'd appreciate any advice I can get about how to fix this functionality in the BAPI or alternatively how to link the pricing condition type to the Scheduling agreement document type?

Thanks so much.
