Payment Block O and P (block for netting ED and FE) ECC6

Question

Dear Experts,
There are 2 payment block indicators that are unclear to us how to use them in our business processes:
1, Payment block O Block for netting ED
2. Payment block P Block for Netting FE
Can you please share your experience in what type of business processes you are using these payment blocks and are there also blocking reasons behind these payment block, like we have for payment block R
Thank you

Hi Ylee,
             Three clarifications from my side in response to your process -
1) Through IMG ---> Material Management ---> Logistics Invoice Verification ---> Incoming Invoice ---> Define Mail to Purchasing When Price Variance Occur, you can be able to set up the message determination so that the related message will be automatically sent to the buyer's inbox as soon as there is any variance between PO price and invoiced amount;
2) Secondly, it is true that once change is made in the PO, the blocked invoice shall also be released through another transaction MRBR.
3) You can also technically define the small difference transaction/event key DIF for automatic posting in case of small difference.
Given your pre-defined process, I would believe that any workflow, once being activated, shall consist of three main steps -
1) The e-mail notification shall be triggered and sent to buyer as soon as there is any variance;
2) Once change is made in PO via ME22N transaction, the workflow will be then forwarded to A/P clerk (invoice creator) so as to either run MRBR transaction or manually remove the payment block indicator;
3) Once this is completed, the e-mail notification will be sent to the buyer (and other related parties, if any) confirming the successful invoice posting.
