Frequent Questions

When a system is submitting an IDSE plan or report to the Information Processing and Management Center (IPMC), can a system log in, work on the electronic file, log out, and come back later?

Systems will be able to log on, work, save their work, and come back as many times as needed. However, once the plan or report is submitted, the system can only make further changes by working with the primacy agency.
