Right now, we are unable posting intercompany invoice with multiple intercompany sales order packing slip because it will be block by error message:

Purchase order: %1 - not all product receipt numbers were found; invoice posting is performed based on quantity alone

Posting

Invoice: %2

Invoice %3 could not post because it contained matching errors which must be approved.

Posting of order %1 canceled

This issue has been reporting multiple times in the past though bug 1092803 and 513318 but we cannot use the workaround as our business require three-way matching always enable for all of the legal entity.

Major purchases in Ansell commercial entities are processed through multiple intercompany entities. Invoices must be auto-posted between these entities to avoid mismatches in intercompany balances. Additionally, for certain countries, a sales invoice is required before the actual shipment can be processed.

If invoice posting is blocked, plant entities will be unable to process shipments, which will disrupt the overall business process. Further, Ansell has indirect procurement scenarios where a three-way match is required, and policy mandates approval if there is a discrepancy between the PO invoice and the vendor invoice.
