Don't restrict too much or too tight, deletion must be possible as it is a prerequisite to archive a PO. The deletion indicator is set by the pre-processing program for MM_EKKO archiving.

Never forget that the invoice still exists technically in the table even after it got cancelled.

There is no customizing, you would need to perform your checks in a BAdI.

Hi Jürgen L, thanks for responding

I told them that in reality and most businesses scenario, the changes in PO is allowed when you already did the GR and IR. Also, the changes of net price in PO after GR/IR won't affect the Finance unless they use that PO for future GR and IR because once they post it the system will generate FI documents.

I tried to convince them, but they didnt change idea. So I would like to know if is there any configuration to avoid the price to be changed in the PO if we have already entered the Invoice in the system.

Once we have the invoice they don´t dont want to be able to delete or change the item in the PO as well

Thanks in advance

Hello ,

Why business need to restrict in this way , as the change in po after is permitted to add new line items to the po .....but changing po price by buyer for an item which is already processed is just ilogical.

Once the po is processed there is no impact on accounting and also the po is delivery completed so user won't able to reprocess it quantitatively.

Buyer must know wht they want to order and which item needs to be changed.

SO its matter of user training to work in logical way rather than restricting by system.

Still business need this them go for a developwment using badi to restrict. No customisation avilable for this.

Thanks

Wouldn't it be good to ask the user why they do it? This often gives a lot of insight and starts a discussion where both sides finally learn something instead of just restricting it (with an ABAP program) without even talking to each other.

And which users are actually doing this change? the buyers or accounts payable people?

What is actually your fear? Does it harm any process? Is it communicated that it harms a certain process?

Jurgen I have a question for you. Once and invoice plan is set up on a PO and once and Invoice is posted and subsequent PO price changes occur will the Invoice plan reflect that price change for the increase in the PO Value? We are using Invoice plan for Milestone payments to vendors on Contracts that span several years for Building a large asset. If the price changes over those years as it could how do I capture that price changes on the Inv/plan for all future dated milestones? will they auto adjust or are there steps required to correct the future Milestone payments.
