Goods Issue from Production Order in SAP

Dear experts,

I faced one issue not yet solve is that my customer created the production order

then already issue for production for all quantities of child item .

Example:

• Production Order
  • Item A
    • Item A1 = 2 Qty
    • Item A2 = 2 Qty
    • Item A3 = 2 Qty
• Issue for Production
  • Item A
    • Item A1 = 2 Qty
    • Item A2 = 2 Qty
    • Item A3 = 2 Qty

But later on, my customer found out that 1 Qty of Item A1 already damaged.

So they want to issue one more Qty of Item A1 instead of one that already damaged.

How can I issue one more Qty for this item?

Please your advices are necessary for me.

Best regard,

Borey
