Is there any way to forbid the MRP for material

Hi ,

Is there any way to forbid the MRP for material ?

Basically , we have an Sales Order / Item / Material of 100 KG. Now upon execution of MRP it has created one plan order of 100 Kg which is converted to Production Order fully.

Now we hav done Goods Receipt of 99 KG and TECO and Production Order.

Still Sales Order delivery for this material is not done. And we want the MRP to forbid the requirement generation of 1 KG for this Sales order.

Regards ,

Upen
