PP-PI: Component withdrawal in presence of scraps

Hi everybody,

to make 1 kg of a product I need 1 kg of a component; but I have 10% assembly scrap (maintained in the product material master) and 2% operation scrap (maintained in the BOM, with net flag settled).

Then I create a Process Order with COR1 and I release it.

Then I confirm 100 kg with COR6N upon this order, and I find that the withdrawed quantity of the component (261 movement) is 92,727 kg.

Can anybody explain to me what calculation is made?

Hy GR,

There is nothing Problematic.its OK

First you have assign 2% Operation Scrap in BOM.

So for 100 kg of Header Material Qty of Component required is 102 kg.Correct.But Here you have do one more thing and that Assambly scrap of 10%.Due to this if you create Order of 100kg system concider 10% scrap and increase the Order Qty to 110 kg among this (10kg is assumed as Scrap).

Now come to the process order

- You have create order of 100kg , but due to 10% assambly scrap qty increase to 110 kg.But you have set 2 Operation scrap due to this system has incresed Component qty to 102 kg(Ignore Assambly scrap of 10% due to Operation scrap).

- Now Come to confirmaiton.

Here what I feel is you are doing the confirmation of that phase with Confirmed yield of 100kg (not 110 kg) without confirming the 10 Kg scrap.Here is the problem.

See the calculation

= 102 x 100 (Confirmed qty) / 110 (Order qty)

= 92.727 kg.

Just try to confirmed that phase with 100 kg yield and 10kg scrap.

System will saw 102 kg of component qty in goods movement screen
