Purchase Requisition is not getting created after relelasing planned orders

Hi All,

We are trying to release the planned orders from the replenishment planning and even we can see its transactions are getting created in SCO with out any error ,but when we are opening the generated document number for the released planned order its status = Closed and there is no requisition details getting populated in it .

We haven't defined any sourcing rule and the expectation is PR should get created without defining sourcing rule.
