Inter Company - Purchase Requisition is not created in Int Purch Direct and Int Purch Trans flows

Hi I am facing an issue where as a business policy, procurement team always requires a purchase requisition and authorization is carried out on the purchase requisition level.

Issue comes when I am running the Inter company flow.

I am using the “Int Purch Direct” and “Int Purch Trans” flows, upon releasing the customer order, pegged purchase order will be created instead of purchase requisition.

Is there a way that I can create a purchase requisition instead of purchase order?

I have set up the default supply option as requisition in the Inventory part planning data as well. 

But for Purch Order Direct and Purch Order Trans flows, Purcase requisitions are getting created.

Did anyone faced a similar situation?

Thanks,

Chamath
