For reporting purposes, the end month is available, but not the start month.
As we work with the business units on their 12 - 18 resource plans, they need highlevel timing (target) of when the release is planning on starting development and when it is going deployed. Having the targeted start/end month for a release enable the business units to plan to support the releases.
Thank you for the idea. This is possible today by adding the release date range start and end dates to a report. The status of this idea was out of date. See the attached images for the Release Date range field and a list report that uses those dates.
