how to block an MM credit memo for payment automatically (MIRO)

[Former Member]

Hello,

due an internal process, the purchase invoice without PO are also posted in MIRO (using the GL account sheet and no or reference). Those invoice without PO are autormatically blocked for payment thank a custo done in the transaction OMR6 AN, then a SAP workflow starts and request to the cost center responsible to approve this invoice. The approval remove the payment block in MRBR.

The accounting team wants to have the same process for the credit memo without PO (so posted also from MIRO) : the wants the item is blocked for payment, and then sent automatically for approval to the cost center responsible who approve the CM and release it for payment.

the problem is the custo in OMR6 AN only block the invoice without PO for payment, not the credit memo. So do you have any idea how we can blocked for payment the MM credit memo without PO ?

Thanks for your help !
