In order for travel to take place, advance authorization is mandatory. Each trip is uniquely identified using a Travel Authorization Number (TAN). The TAN remains assigned throughout the life of a trip, uniquely identifying the trip from the planning through to the expense reconciliation. Each TAN is associated with a department or agency, branch, directorate, division and/or work group unit, and each TAN is linked to a Departmental Travel Expense Account (DTEA). The TAN is required for all travel requests, including expense claims only i.e. no travel segments.
The TAN system module described in this Help System allows for the generation and administration of offline and emergency TANs. The module also lets you validate offline TANs and manage specific users. The system is role-based so different users have access to different parts of the site.
The module accommodates travel and expense management for the two different types of GoC departments:
Full-solution Departments - Departments use all components of the solution including the expense management tool which includes travel authorization and automated TAN issuance.
Modular Departments - Departments use all components of the solution except the expense management tool. These departments have alternate tools or paper processes for obtaining travel authorizations and issuing TANs upon approval of the authorization.
