How to use approved supplier list for internal requisition

Hi All,

We are on Oracle EBS 12.2.9. We are looking to use internal requisition for raising internal sales order across different regions within the company. When one internal organization orders from another internal organization business would like to introduce restrictions on which item can be sourced from which internal organization. Some items for instance cannot be bought from our company plant located in US to be shipped to our company plant in UK. Business would like to use the approved supplier list for raising internal requisition.

However as i understand since the source of internal requisition is inventory organization and not supplier , in case internal requisition the approved supplier list is not checked.
