Vendor Line Item display/ and Purchase order Field
We recently implemented the MM PO module in SAP, we are creating PO's automatically in SAp from a 3 party system. We are using field "Our Field" EKKO-UNSEZ to enter a reference from the 3rd party system. Our account payable have requested that they need this field to display in FBL1N "Vendor Line Item Display". I tried by using special fields but table is not available. Anyone has any suggestions? I know I can use BSEG and EKKO but it is too big of a table to use. Does this requires more of an ABAP report rather than just a simple QUERY report?
Your suggestions are appreciated.
