Which category of requisitions will always be assigned with a DTO series document number?

• A. EQUIPMENT REQUISITION
• B. MATERIAL REQUEST
• C. PERSONNEL ACTIONS
• D. SERVICE RELATED

Answer: (D)

The key idea is that DTO series numbers are designated for service-related work. When a requisition involves external services—like maintenance, repairs, or other contracted work—a DTO number serves as a unique service work order identifier. It ties the requisition to the service contract, tracks performance milestones, and links to invoicing and acceptance. This numbering helps ensure clear accountability and traceability throughout the service engagement.

Equipment requisitions and material requests are typically part of internal supply and inventory control, so they use standard requisition numbers designed for stocking and issuing tangible items. Personnel actions relate to HR processes and have their own tracking identifiers, separate from service work orders. Because of these established practices, service related requisitions are the ones that are always assigned with a DTO series document number.
