Changing a PO to multiple account assignment even after Invoice

[Former Member]

Hello Guys,

I'm currently looking at a PO with Account Assignment Order and Item Category Service. We're currently encountering an issue here as there's still an open commitment to this PO even if the quantity has been adjusted, final invoice flagged, ran RKANBU01, etc.. anyway.. that's another issue (delivery completed flag is hidden in the PO, and we have yet to 'tick' it by changing the config) .. what I saw is that the account assignment was changed to multiple account assignment AFTER the PO has been GRed and Invoiced, what happened was the user was able to change the account assignment of the PO to multiple account assignment. I would like to know how this is possible as I cannot replicate it in our test boxes. I also think this is why there's a floating commitment in our order.

Can someone help me on this?

Are you using BAPI_PO_CHANGE in your process?

there is an OSS note fixing an error: 1736712 - BAPI: BAPI_PO_CHANGE changes accounting fields incorrectly

Hello Jurgen,

I don't think so, I also talked to the user and it seems like she has no clue how this one happened.

As an additional info:

• The PO Service tab, previously contained 3 lines of services of different quantities and carries the same Service No.
• 2 of the services were created an accepted SES of their own, one for full Qty, one was accepted for partial Qty.
• Both were invoiced.
• After 3 months or so, the 3rd service link that wasn't created a SES was deleted.
• The 2nd line's quantity was reduced to a quantity that will make the commitment disappear.

Then based on the item changes, the account assignment was changed from single to multiple. I tried searching for sap notes or maybe it's a basic functionality but i wasn't able to find one. So if anyone has some inputs or theories I would appreciate it. thank you!
