PO is Creating instead off Material Stock Request Via using the Quick Sourcing.

hi all,When User create the requisition through the eProcurement so He/She has two ways to source the requisition.
1) Through the Quick source.
2) Requisition Expedite.
Here I am sourcing the Requisition Through the Quick Source, Which has the functionality to Create Material Request request or PO, but when I am  running the Process through the quick source
the PO is creating instead off material stock request. Kindly find here an attachment which shows the full flow and reply me accordingly.

But here client’s requirement is to create the Material Issuance Request for the Items present in the Store, and we have purchasing, eProcurement and Inventory module implemented. Please help us to understand how to capture this scenario??
