I have a problem: I have a schedule that is baselined, constructed using horizontal and vertical logic, constraint free, fixed duration. I have a work package / task that has a FS dependency. The predecessor is not finished; however, the dependency is soft and we were able to start the successor. I want to enter the actual start date but, when I do, schedule removes the start date and replaces it with NA. It will also not allow me to update the percent complete.
The weird thing is, I have a duplicate task in another control account, same dependency, same duration, same set up, and it did allow me to enter an actual date.
What could be the cause of this?
Update: I need help asap. Hypotheses are welcomed!!
