Goods Receipt Tolerance Checks with scheduling agreement

Hello,

Weused scheduling agreement to order components.

We made our goods receipt with inbound delivery (VL31N) in reference at our scheduling agreement.

I would like to implement goods receipt tolerance check on the inbound delivery.

The problem is when I put tolerance in the info record (5% for example) the system check the tolerance with the total quantity of the item and not for the quantity of the schedule.

Does anyone know how to based tolerance check on the quantity on the delivery schedule expected and not on the total quantity of the scheduling agreement item?

Best regards.

Gwen
