Migration of Purchase Order History using RM06EEI1

Hi

I have migrated Open Purchase Orders from one SAP system to another SAP system.

I have loaded the Purchase Order details using business object BUS2012 and the PO History using program RM06EEI1.

Only open quantities were loaded to facilitate subsequent Goods Receipts and Invoice Receipts.

The records were loaded without errors.

The Material Ledger was inactive during the migration and activated after the migration.

Everything looks ok from a migration perspective. The correct quantities are created on the PO, the GR shows on the History tab, and the correct GL Accounts were posted to i.e the GRIR Clearing Account and the IR Account.

However, I am unable to perform Invoice Verification (MIRO) and Reversal of Goods Receipts (MIGO) on these records.

The error message is "No (suitable) item found for purchase order".

Has anyone encountered this scenario and can shed some light on this issue?

Regards

Magan
