hi:

sales orser item A qty is 100 pcs. But i want to genetate item A qty is

100 * 120%=120 pcs in Planned Production order ?

Who can help me?

If you're working from the Item master plan, Just add 20pcs additional demand on the related bucket and regenerate again. it should now generate 120 planned production order.

or, if your production order is already transferred for execution and you're sure that the material is sufficient, just simply change the planned production order qty

Investigate scrap & yield

use scrap & yield only change qty planned but don't change oeder qty

use scrap & yield only change qty planned but don't change oeder qty

100 * 120%=120 pcs in Planned Production order ?

I don't think the requirement is to change the Sales Order qty, just the Production order

100 pcs in Planned Production order. Not 100 * 120%=120 pcs in Planned Production order ?
