Slightly OT: Adding PO items to MM invoice from workflow

[Mike Pokraka]

Hi Ramki,
I was trying to keep it too simple... 4.7 / 620. MIR4 -> Edit -> Change
The process:
- Incoming invoice scanned and entered automatically using OCR.
- If OCR cannot post invoice, it's parked & WF triggered
- WF determines user and asks them which PO items this invoice is for
- Done in custom popup with list of open PO items against vendor,
- Client doesn't want MIR4 because this way is a) a simpler interface 
and b) restricts header changes.

We have found BAPIs and functionality galore for CREATING invoices, but 
not for changing them.... Adding items in this way seems not that 
unusual a requirement, are we really alone?

Thanks
Mike

We've gone through BADIs', BAPI's, OSS, SDN and various SAP sites, messed about with MRM_* function modules (chaos!), at last resorting to writing a BDC (ugh) which uses MIR4 - but only works for up to 8 items (there's no page down in the PO selection popup from MIR4).
