Assembly scrap not considered in final product

Hi everyone,

we have a situation when planning for our production.  We have the assembly scrap maintained in the material master for our final product:

However, Receipt Qty and total quantity in the planned order is the same amount although it should differ. We have both at for example 40.000, although we would expect that total quantity would be at 42.000 in order to reflect the 5% scrap. We do not have any other scrap like component scrap or operation scrap. Also we did not set the flag Net ID. What could be the reason for this? Is it possible that the boom usage we have, i.e. engineering/design prevents the scrap from being added?

Thank you in advance for your help.

Best regards

Mitch
