Is it a correct Functionality ?

Hi,

 

I created the inventory Item, CPA Contract Purchase Agreement, Sourcing Rule, Assignment to Approved Supplier List and the Price List.

While generating the purchase requisition, I enter the item number, system displays correct Description and UOM.  System keeps the Quantity and Price as Blank field. Then I click on Source Detail TAB and under document type MANUALLY I selected “Contract Purchase Agreement” and document number. This action feed the unit price in Line tab from the Price List.

Why system is not defaulting the price from the price list. Is it a mandatory step to click on Source Detail Tab and select Document type and document number? Is it possible to default like how we are getting unit price from quotation.
