Change Account Assignment Category in Purchase Order - URGENT
We are in SRM 4.0 Extended Classic Scenario.
We have the following problem: If we try to modify the item account assignment category (for example, from cost center CC to fixed asset AS) of an existing purchase order, the system doesn´t allow us to modify it, it only permits to modify the account assignment object (the cost center number for example).
The purchase order has been created manually (not from a shopping cart), and there aren´t any confirmations for this purchase order.
Is this the "correct" operation of the system or there is some SAP note about it?
Thanks very much and Regards.
