Unable to change task constraint when set to 'Fixed Dates'
We have noticed a behavior where sometimes tasks with the 'Fixed Dates' constraint doesnt allow you to change it to additional constraint types. I can make a copy of the project plan, and on the new project the 'Fixed Dates' tasks allow me change the constraint type. This tells me there isnt anything wrong with the task its self as the same task on the copy changes with no issue. Does anyone else have any experience with this having and understand the cause? I have users create a new task with the desired restraint and delete the old one as a workaround solution.
