Able to cancel or finally close the IR, against which the material has been received

Hello,

I am able to cancel or finally close the internal requisition against which internal requisition is created and also the material has been received in the requesting organization.

But I am not able to do the same for internal requisitions for which internal sales orders are created but not picked.

Is it standard system behaviour? If yes, can you please guide me to the part of the Purchasing User Guide or Order Management User Guide that says so? Because I have gone through both of these and could not find relevant text.

I found two notes as below.

1115556.1 :- This note says that the system allows to cancel/finally close the internal requisition even though open sales order lines exist.
