For the automatic cenvat clearing , We are using assignment filed populated as "Po-Number & PO Line-Item No" . This is working fine except for entry created thru J1IH .
In J1IH created entries , the assignment field is "00000" . I explored the subsitution (GGB1) also , but could not figured out that how can the PO Number/Line-Item information to be made available in the subsitution module .
I request members to kindly help me with your guidance .
