Production Planning - Planned orders and backflushing: REM

Planned orders - Material Requirement Planning:
Often, on the shop floor, there are certain materials which fall short. The first step towards ensuring that the procurement of a plant material for a certain quantity for a specific date occurs on time is the planned order.
Table - PLAF
Field - PLNUM.
Transaction to create a planned order - MD11.
Related tables - KBKO (Changes are reflected here when values of PSTTR, PEDTR are changed via MD12).
Planned orders, as is usually the case are connected with other related modules, the most striking being Inventory Management.
The question is, what is done after the materials are bought? When it is made available.
Backflushing comes into the picture. SAP glossary states that "The goods issue posting for backflushed components is performed automatically at the time of order completion confirmation".
Transaction - MFBF, MF70.


There is another case when there is a physical withdrawal for an order - Non-manual posting of issue of components is needed here.

The clerk working in the shopfloor in the REM industry would be acquainted (repetitive manufacturing)with some of these terms.
