Charging account assignment for PO with SES

[MokraneAbdessalam]

Hello, I have a Purchase Order that was created with the incorrect account assignment. There have been multiple service entry sheet and AP Invoice as well. I would like to change the account assignment to the correct one at PO level, so that future SES will go against the correct object. Can this be done? Thanks!

Hi @MokraneAbdessalam,
If PO Item has PO history, then system will not allow to edit the Item level account assignment tab details.
If Invoice is not cleared for payment, we may reverse the Invoices and SESs, then create a new line Item in the PO for the same requirement with correct account assignment and then delete the existing line Item.
If the reversal is not possible, short close the Item by removing open quantity and Create a new line item with remaining open quantity  with correct account assignment.
