We have a requirement to populate the Assignment field(BSEG-ZUONR) in the Accounting document that gets generated via RD04 IDOC(INVOIC02) with the Billing document Reference number(VBRK-XBLNR).
We have this data being populated in the IDOC Segment E1EDK02 Qualifier 87 but need inputs on how to pass this value to the field BSEG-ZUONR.
Many discussions in the community provide solution where BSEG-XBLNR need to be copied from VBRK-XBLNR but we are looking specifically for BSEG-ZUONR.
Any inputs on this is appreciated.
Thanks and Regards
