As of Release 4.0A, you have the option of changing the account assignment category in purchase requisitions and in the external purchasing documents purchase order, contract and scheduling agreement. You determine whether the account assignment category can be changed via field selection in Customizing.
You can make the change in the document itself or in the next document in the procurement process in each case (e.g. in a purchase order created with reference to a requisition). You can also switch from account assignment to no account assignment and vice-versa.
If you change the account assignment category, the system checks the existing account assignment data. If the latter is incomplete, the account assignment dialog box appears and you can supply the missing details.
You cannot change the account assignment category
The account assignment category cannot be changed in service items.
