PR workflow Issue-what is the link between workitem ID and PR # at database

Hi Folks,

in the Purchase requisition workflow, how do we know the relationship (link) between Purchase requisition No and workitems ID. there are so many workitems for each purchase requisition but one common link should be there between one purchase requisition to all other workitems related to this PR.

How do we know the link between Purchase requisition and the concerned PR workflow in the SAP database.

Please provide the solution for the above, it is very important for me.




Hello Ravi,

you can use the function module


(more simple call)



(more release-safe but more complex)

to retrieve the work items for each requisition.

Set the ObjType to BUS2105

Set the ObjKey to the requisition#

Best regards,
