Which of the following is not a purpose of DTS groups?

The purpose of DTS groups primarily revolves around enhancing the travel process for users, which includes facilitating communication and streamlining approval processes for travel requests. The selected answer is correct because providing Routing Officials access to a travel document during the routing process does not align with the main functions of DTS groups. Instead, DTS groups are more focused on aspects that improve user experience and collaboration among travelers, ensuring efficient management of travel expenses, and expediting the approval process related to travel requests.

In contrast, facilitating communication among travelers and managing collective travel expenses are integral to the operation of DTS groups, ensuring that travelers can coordinate effectively and keep track of shared financial responsibilities. Similarly, streamlining the approval process for travel requests allows for more timely travel management, benefiting both the individuals and the organizations they represent. Therefore, the correct answer reflects an activity that is not a key function of DTS groups.
