If confirmation processes are to be processed in the background, you have to decide when the individual processes are to take place. As a general guide:

• Automatic goods receipts should be processed soon after the actual confirmation. This applies to materials that are processed further or that are needed in Sales, for which it is particularly important that stock levels are kept up-to-date. Processing should be online or executed as an update task.
• Backflushing withdrawals can be processed in longer periods (for example twice a day). Since the material has already been withdrawn physically from the storage location, stock levels are not as important. However, other consumers of the material and material requirements planning should be notified.
• Actual costs determination can take place less frequently (for example once a day). Actual costs determination is not important for smooth production processing. It is needed for controlling and should be adapted to the demands of this department.
