Posting Separately by Business Area
If you have determined that the payments for a certain company code should be made separately per business area, then the bank posting is made to the business area of the paid items.
If you do not separate the payments by business area, you can specify that the bank postings should be made to one certain business area. To do so, specify the required business area for the bank account (see the figure above).
This specification is only effective if you do not already pay separately by business area.
In all other cases the postings to the bank subaccounts are carried out without reference to business areas.
