Diagnosis
You tried to change the business area. You should only do this if thereare no items with subledger postings (such as advance payments) thathave been directly or indirectly assigned to the real estate object.Otherwise, this could lead to inconsistencies in the balance sheet ofthe business area (for example, if the new business area for the realestate object were to be used for payment settlement or reversal).
Real estate objects lower down in the hierarchy inherit the businessarea of the level above (for example, the business area for businessentity also applies for the buildings, property, rental unit andlease-out), unless the business area is entered specifically for thesub-level. As a result, changing the business area for a businessentity can also be critical, because this implicitly affects open itemsof the lease-outs.
Changing the business area can be critical in the following cases:

• Reversal of a document that was posted with the old business area


• Service charge settlement, if advance payments have been posted
using the old business area

• Clearing items with the old business area

Procedure
If you want to change the business area anyway, even though open itemswould be affected, you must first transfer all the affected documentsto the new business area manually, and then change the business area.
If you are using the Cash Management component, you must regeneratethe cash flow after you have changed the business area (transactionFOVB). The system then adjusts the business area view in CashManagement automatically.
