Calculate backflush quantity

If you report the total ordered quantity as completed, the material quantity that is issued through backflushing equals the estimated material quantity.

If you report a part of the ordered quantity as completed, the material quantity to issue is calculated as follows:

Backflushed material quantity = 
Estimated quantity x (Quantity to backflush / Quantity planned input)

• The quantity-planned input is the ordered quantity, corrected for scrap and yield on the operation.
• The estimated quantity that appears in the Estimated Materials (ticst0101m000) session.

Any scrap on the material that you do not define as a percentage but as a fixed quantity is issued all at once as soon as backflushing is carried out. You can define these scrap quantities in the following sessions:

• Estimated Materials (ticst0101m000)
• Production Planning (tisfc0110m000)
