Good question, Doug. I never had an issue with the date when sending a task back to work requests but did some testing just to be doubly sure…
I clicked on "Work on It" for one of my Tasks "not ready" to start that has a planned completion date of September 12. It showed in my Working On list, as being due on September 12 whether I sorted by Planned Completion date or Commit date. I sent it back to Work Requests, and it now shows as 'not ready' to start again with the September 12 date.
Next, I clicked on "Work on It" for the same task, but then changed my Commit Date on it to September 9. It showed in my Working On list, as being due on September 12 (original planned completion date), when I sorted by Planned Completion date, and as being due on September 9, when I sorted by Commit date. I then sent it back to Work Requests, and it shows as 'not ready' to start again with the September 12 date. So, it removed the previous 'commit date' (Sept 9) and kept the original planned completion date when moving it back to work requests -- it did not materially change anything when sending it back, essentially it set it back to its previous 'not ready' parameters.
