Requisition nodes build a hierarchy to group the underlying templates and the associated requisitions. The requisition nodes are assigned to the MTO type to include all underlying requisition templates in the MTO job. If inquiries are issued on known material groupings based on previous experience and standard company practice, the requisitions must be broken down in a way that assists the procurement discipline. For example, large-bore gate valves may be sent for inquiry to a different supplier from small-bore gate valves or check valves. If this is the case, it is necessary to specify a different node and template for both items.

For example, the master node of a requisition node structure would be the Piping discipline, with these sub-nodes:

  • Pipe

  • Fittings

  • Valves

  • Gaskets

  • Other items.

Each of the nodes would have templates assigned for different material types like:

  • Carbon Steel

  • Stainless Steel

  • Alloy

  • Non Metallic.

Do not modify the template definition after requisitions have been generated. The calculation of quantity changes is based on consistent node structure and template definitions. The quantities calculated based on the new/modified template are not comparable to the requisition quantities calculated based on the original template.
