Create PO when SC total price is less than 500

Hello Gurus,

Recently, business has a requirement.

The requirement is whenever the total value of the shopping cart is less than or equal to 500MYR and vendor is known, (after approval process) , system will auto create Purchase Order.  If the vendor is not known, system will create a Purchase Requisition in the backend eventhough the value is less than or equal to 500MYR

By standard, system does not check what value is it in the shopping cart as long as the information in the shopping cart is complete with vendor and price, and in the customizing we configure that the purchasing group will create PO , backend it will create a Purchase Order.

Last year, Purchasing do not want the free text shopping cart to create Purchase Order and as far as I understood, in EBP,  there is no such thing that is able to separate free text and catalog shopping cart since the business object is the same.    So I make use of the standard SAP standard customizing.

Thus, at that point of time, I played around with the authorization object (role) and remove the " Supplier"  so end user will not be able to enter the supplier in the field and end up system will create a Purchase Requisition for Free Text shopping cart
