In document posting in the FI system, an entry tool is available as of 3.0A for the account assignment of business areas, provided that the Business area balance sheets in the company code table are activated for all involved company codes.
If exactly one business area occurs with the manually entered lines, this business area is duplicated into all other manually entered lines. Automatically created line items are not changed since the business area here is generally derived internally.
If the posting is created via batch input or by call transaction, no business area is substituted in order not to falsify the data of the sender.
To enter all items with the same business area in a document, you only need to enter the business area in one item. During document entry, the system enters this business area into all other manually entered lines.
