Purchase Requisition is not getting close

Hello All,

We had a issue where after creating RFQ, quote and purchase order form Purchase requisition still PR is not getting closed.

For example :

Example	Purchase Requisiton	RFQ	Quote	Purchase order
Example 1	100 Qty	100 Qty	100 Qty	100 Qty
Example 2	100 Qty	50 Qty	50 Qty	50 Qty

In first example when we created purchase order( which is approved and closed) with full PR qty still PR i not getting closed.

In the second example when create PO with partial qty, next time while creating RFQ, qutoe and PO PR qty is showing full where as it should show 50 qty.

Could any one suggest is this normal behavior or should i log SR.
