No delta records for data source 0SRM_TD_PO_ACC

Hello,

I have activated the datasource 0SRM_TD_PO_ACC in our SRM system and then initialized the delta load. But no delta records are coming into RSA7 and hence to BW. Have I missed out any other configurations?

SRM version: EHP2 FOR SAP SRM 7.0 (Package level: 6)

BW Version: SAP NetWeaver AS ABAP 7.31 (Package level: 6)

Has anyone else come across a similar issue before?

Thanks,

Emir Vural
