Requisition Worksheet

Hi all I have a question maybe you can help with.

Say we have a widget that is LOT for LOT and has no safety stock with no re-order point. We have 2 on PO and only one is received. We have a component demand for one and whats happening is when we run requisition worksheet it doesn’t see that there is one still on purchase order and tells us to buy again.

How can we make this stop?
