Wrong calculation of Operation Scrap qty


My Scenario is:

When i created a Production order for ex. Total qty: 206 BOX., in the operations overview screen the operation qty varies based on the scrap percentage maintained in the operation.

Op 1- Operation Qty: 206

Op 2- Operation Qty: 206 - Scrap % : 2.912

Op 3- operation Qty: 200

Op 4- Operation Qty: 200 - Scrap %: 50

Op 5- Operation Qty: 100

Op 6- Operation Qty:....



(Header material has 106% as Assembly scrap in Material master, So if enter 100 as total qty required in CO01, it is automatically changed to 206 based on the Assembly scrap %)


If I go to Qty/ activities tab in Op. details of Operation no: 4

the operation qty is 200 & operation Scrap 50% But Scrap qty is coming as 101.

It should come as 100 instead of 101.

(Operation scrap % is maintained in routing. Not in BOM)

Please tell me how this qty is being calculated. Will there be any dependencies ?

Thanks in Advance

    hi senthil,

    This might be because of 2nd operation scrap percentage(2.912% of 206 is 5.99872). i.e After scrap you will be getting yield as 200.128 and in next operation as 100.064.System might be considering as 101.

    Now you change the 2nd operation scrap percentage to 2.913( 6.00078) and check it.

    revert back after checking.

      When i changed the scrap % to 2.913, the scrap qty became 7.

      The further changes:

      In op 3- Operation qty: 199

      in op 4- Operation qty: 199

      in op 5- Operation qty: 99

      if i go to Operation details screen for Op 4, the scrap qty: 100.

      Please let me know your feedback.

      Thanks and Regards,
