Update Multiple PRT measuring points manually on PP confirmation

Hi Expert,

We implemented counter base PM for PRT and measuring points are count upon production order confirmation (PRT assigned to PP order operation)

I have a scenario where I need to assign two PRTs (PRT1 & PRT2) into this operation and counters are updated evenly

(If the PP confirmation is done for 10 products PRT 1 counter 1 and PRT 2 counter 2 increase by 10 )

I need manually change the counter increasing quanty while doing the PP confimation eg: for counter 1 by 6 and for counter 2 by 4

Is this possible in standard CO11N screen?

Please help me with alternative

Thanks

Ashok
