During the design phase of a capital project with multiple EPCs, centrally generating and reserving functional location tags can prevent duplicate tags and the consequent rework and revalidation that may occur if tags are independently created by EPCs. A user may directly request new functional location tags from a tag management application or via an engineering tool; this Use Case addresses the latter scenario.

Furthermore, functional locations are generated in context of a document. For example, when drafting a P&ID, a series of piping tags may be requested; or a data sheet document may be created for a tag. The document-functional location association can be made known by an engineering design tool to the tag manager application or ECM system.
