Posted invoice keeps parked items and blocks PO items (SAP ERP 7.40)

[former_member812187]

Hello,

my first post here.

We have some vendor invoices, which we processed through xFlow.
Example: Purchase order with 2 item lines. While processing the invoice in xFlow, we add the "purchase order line items" to link the purchase order items to the invoice (I think it is rather basic and usual).

PO has 2 items, but only 1 of these 2 items are invoiced.
The accounting block in xFlow looks like

ITEM PONUMBER POITEM QTY AMOUNT
1 3838383838 10 10 99999
2 3838383838 20 0 0

Then the invoice gets posted and paid.

THEN in the "document", item 2 "disappears". When going to the xFlow "thing", it is still visible in the accounting block.

Now the problem I have is this. I need to delete the item 20 in the PO, but SAP says, there is a PARKED INVOICE, which is also visible in the PO history, but what he sees as parked invoice is the POSTED INVOICE!

How to solve this problem? We have many "blocked" po items due to this issue!
If your answer is: reverse invoice, please do not reply.

Thank you!
