We are having a subcon po for a header material XXXXX with quantity 380 cs and providing 2 components A & B of 2 ea. we have done GR for 380 cs as 190 cs in 1st GR and 190 cs in 2nd GR and the components been consumed as 1 in A 1 in B for 1st GR with mov.type 543 and for the 2nd GR 1 in A and 1 in B. so both A& B of 2 ea is been consumed. But my questions is, how system is taking 1 ea in both A&B for both GR correctly. if i had put the GR as 150 cs and 150 cs and 80 cs. how it would have separated the components ?? how components are getting separated proportionately ? kindly clear me please.
