The flexible upload task is used primarily to import files that contain financial data from non-SAP S/4HANA consolidation units.
In our scenario, the United States and German consolidation units are in SAP S/4HANA. However, because this is a start-up scenario and not all historical data is in SAP S/4HANA, we are importing data for all of our consolidation units (including the United States and Germany).
After this start-up phase is over, the United States and German consolidation units' data can be released from accounting.
