How to stop automatic creation of Purchase Requisition before without approving the Incoming Customer Order

Hi All,

Currently facing the issue during customer order process. Created the CO line with “supply Code: Int Purch Dir” and released the CO. Then, demand PO will be created against the CO line. 

Finally before approving the “Incoming Customer Order”, automatically Purchase requisition is created in Planned status. 

I have tried with running the MRP before approving the “Incoming Customer Order”. 

But system should not create a Purch Requisition before approving the “Incoming Customer Order”. 

So kindly suggest to stop the generation of Purch Requisition before approving the “Incoming Customer Order”. 

Thanks in advance for your understanding.
