Quantity transfer from doc to its refrenced doc if some qty is rejected

Dear all,

Please find my query ,

If B is doc type referenced from A

A: 100

B: 50

so remaining qty in A is 50.

But if i reject 25 qty in B, this qty should be added to A.

So A should be 75.

Please let me know the procedure to do this settings.

Thanks & regards,

GHS
