Closing item Qty.

Hi Everyone,

Can anyone help me how to close item qty in purchase order here my scenario is in one purchase order if there are 3 line items (A,B,C) each item is having 10 qty and only i'll make GRN/ GRPO for (A=2; B=10; c=10). So my problem here is I need to close remaining 8 qty of 'A' in the respective purchase order. Kindly give your valuable suggestions in this scenario.

Thanks & regards
