Backflushing procedure

LN carries out backflushing according to the following procedure.

Step 1. 

Backflushing starts when you report a quantity as completed or rejected in one of the following sessions:

  • Report Operations Completed (tisfc0130m000) session
  • Report Orders Completed (tisfc0520m000) session
Step 2. 

The default quantity to backflush is calculated as follows:

Quantity to backflush = (Quantity reported as completed + Quantity reported as rejected) - Previously backflushed quantity

The Qty to Backflush field displays this default quantity, which you can modify.

Step 3. 

The next step depends on the value of the Backflushing Method field in the Shop Floor Control Parameters (tisfc0100s000) session:

  • Automatic: backflushing proceeds without user interaction.
  • Interactive: LN asks you if the backflushing must take place.
  • Manual: you must use the Backflush Materials and Hours (tisfc0220m000) session to carry out backflushing.
Step 4. 

LN processes the issued materials and the accounted hours:

Note

If you use backflushing you can still record additional quantities to issue and account for additional hours in the following sessions:

  • Material to Issue for Production Orders (ticst0101m100) session.
  • Through the Hours and Expenses by Employee Overview (bptmm1100m000) session. LN adds these quantities and hours to the backflushed quantities and hours.
