S/4Hana Cloud. 

1. Create Purchase Requisition
2. Enter the necessary parameters for the purchase requisition
3. Enter Purchase Requisition line item
4. Enter Account Assignment
5. Enter Functional Area
6. Save and then check the Functional Area field, it is blank

The functional area is required to create a profit and loss statement for Financial Accounting using cost of sales accounting. Logically it does not make sense to populate functional area for balance sheet accounts especially not for an asset accounting account. 

The functional area is removed in the Purchase Requisition with accounting assignment "A" as intended.
