Who would you forward a request for an advance decision when faced with a questionable payment in DTS?

When faced with a questionable payment in the Defense Travel System (DTS), you should forward the request for an advance decision to your designated approving official or the travel manager within your organization. They are responsible for reviewing unusual payment issues and can provide guidance or make necessary decisions. Additionally, if your organization has a finance or accounting department, they may also need to be consulted for further clarification on the payment issue.
