Data Exchange: Upload 
After optimization, you can start a transaction in the SAP system to trigger a transfer of the changed data from the optimization system to the SAP system (data upload). This is a synchronous data transfer called RFC (Remote Function Call) that ensures data consistency in the SAP system.
After the data has been uploaded, you can access the planning table or the stock/requirements list to display the results of optimization. In addition, you can check the received data log to make sure the data was successfully transferred..
The following data changes are transferred during an upload:
Changes to planned, production, and process orders, for example:
Date
Quantity
Selected routing (with production version)
Selected bill of material (with production version)
Changes to operation, for example:
Date
Standard values
Work centers/resources
Creation/deletion of planned and production orders
Caution
The long-term planning data (planning scenario) cannot be changed by the upload. Only productive data can be changed.
Configurable materials are not supported by the upload of orders.
The planned orders changed using the interface are automatically fixed. Requirements planning in the SAP system cannot change or delete these planned orders.
Note the requirements for exchanging data using the Production Optimization Interface (POI).
