Purchase requisition Table in SAP SRM

Hi Gurus,

We are using SAP SRM 7.02 and ECC 6.04 in classic scenario. Process flow is like :- PR is created in Back end system and is converted to RFx in sap srm system via CPPR process.

Once RFx is created it gets updated in table Eban_tech but where does PR from Back end system gets updated in SAP SRM.

PLEASE NOTE THAT PR HERE IS NOT FOLLOW ON DOCUMENT.
