You use transaction FS10N to display balances for general ledger accounts. When you double-click one of the rows, you access the line item display (FBL3N)
When you do this, you notice a difference between the balance display and the total using the displayed items.
The 'document splitting' is active in your system.
These problems occur in the following constellation:
1. The document splitting is active.
2. You have assigned the 'Business Area' scenario.
Transaction FS10N reads the balance table for the new general ledger.
With active splitting it can occur, that balances and line items for specific accounts receive a 'business area' information, which is NOT updated in the Entry View of the document.
In the case of a drilldown to the line items, this 'selection' of the business area is transferred as a selection criterion.
However, as the business area might not be stored in the line items (BSIS/BSAS), these documents are not returned, or get wrongly displayed.
