Assembly scrap effect on cost estimate

Hi All,

When I am changing assembly scrap % in material master ans rerun cost estimate kkf6n...the values change ..Is this a standard behaviour, cause when I am doing MFBF for planned order 100 with scrap 10 (total 110) it gets reduced from MD04.

Please guide.

    Yes this is as per standard SAP system design.

    When you execute a cost estimate for a material it consider assembly scrap.

    You post backflush to a material with planned assembly scrap. The planned assembly scrap is taken into account for default quantity GR should be for 100 and 10 as scrap and total GR quantity 100 same as per planned order.

    Best Regards,

    Hi Rupesh,

    But in REM, when we do back flush of 100 even if order show 110 including scrap of 10, it gets completely consumed.If I do gr of 105 parts the extra 5 quantity is consumed from next planned order.

    So practically it is only increasing cost and GR in actual is only for 100 parts also there is no posting of scrap as well.

    • Hello,

      If 110 pcs (yield!) are backflushed in the above example, the planned order is overdelivered, that is, more pieces have been produced than required. The planned scrap has only the purpose to generate additional dependent requirements.

      Please refer SAP KBA 2029238 - Scrap component at MFBF on it.

      Best Regards,
