Equipment obtained through the SSD Regional Supply Center provides uniformity and quick purchase time. This is the most economical way to purchase equipment because warehouse stock is purchased in larger quantities. Districts may order equipment from the Regional Distribution Centers by submitting an "Inter-Unit Transfer" request through the PeopleSoft Inventory module, or by submitting an "EPRO REQ" through the "Purchasing" module in PeopleSoft. The NIGP # will be required for each item requested.
