|Blocking the PO
Is there any way to block the PO , so that no GR can be possible?
Is it available on header level?
There are three ways to close/block purchase order:
1. Change P.O Quantity equal to delivered quantity.
2. Select line item in p.o, click lock icon to block it.
3. BADI for delivery completion indicator.
Blocking is not possible at header level.
To prevent a GR posting, you can proceed as follows:
1) Reduce the purchase order quantity to the previous GR quantity.
2) Block the purchase order item.
(ME22N: Block pushbutton; ME22 Menu -> Edit -> Block)
Fill the date field for the 'Latest Possible Goods Receipt' (LEWED)
in the purchase order item. If you do this and you enter a GR document
after this date, the system issues message M7163, which you must set as
an error message in Customizing.
See OSS Note 856279 - MIGO: Proposed qty despite 'delivery completed'
By the way, setting the block is not really recommended and should
just be a short term solution, as it will stop you from archiving this
PO and not really close the business case. and even blocked POs are still
considered in MRP
