Supplier Intransit Times

Hi All -

The Business Users have a requirement to track Supplier Intransit Times in EBS. I understand that we will need to set up Supplier Locations in Regions and Zones.

I understand that we can do this by running the Location to Region Mapping and Region Interface requests.

Our question: Is there a way to manually load the Supplier Locations in Regions and Zones? If we use the requests above, the system will also include all Customer Locations, which we do not necessarily want or need.

Thanks in Advance
