Partial WO completion for fixed batch quantity

Hi

We are using fixed batch quantity for BOM in E9.1. When we do the partial completion thru superback flush , the issued quantity values of components(P31113) are not defaulting the corresponding calculated values for partial completed quantity. For eg, if we define the component #1 as 50 qty required for 100KG batch quantity in BOM. When we do the partial completion of 50KG, then P31113 (issues) displays Issues quantity as 50 for component # 1 , instead of 25.

Is there way to default the component values as per partial completed WO quantity ?

Regards
