Good Day. I use 7.5. sp3. I have an project with work plan created from PPM directly. Also I use Time Management to reporting time to task. Question: I need upgrade work plan from MSP (add approximately 400 tasks). How it possible Thanks in advice.
(1) change your project's MSP integration to 'Shared', download the workplan to MSP, add your new tasks there, upload back to PPM, reset integration to 'PPM'
(2) create a dummy project without a workplan, upload the new tasks to this project from MSP; in your original (target) project's workplan highlight the last task, click Actions -> Import another workplan and select the one on the dummy project.
