Thanks for trying Christopher Canham but those don't work.
Kludge 1, because of caveat #2 -- A project of any size will have summary tasks. Mine has many summary, as well as sub-summary tasks (3 or more deep hierarchy.
Kludge 2 -- Asking that I out-dent all of my summary tasks to make the tasks line up. Far too labor intensive, and fraught with error in restoring my summary tasks.
Kludge 3 -- Already addressed in my post of 1/12/23 -- Last paragraph. Upon importing the .mpp the assignments are lost.
Hoping to try out the Project Template, just logged into O365 looking for Dynamics under Waffle -- nope, not there. Searched all of my apps -- no Dynamics. Attempted to add Dynamics. Not found.
jackieduong"Copying a project does not copy over task assignments or the connected O365 group. However, you can always re-assign the project to the same group (or a different one!)." Unacceptable! When will this BUG that looses data when copying a project be fixed? It has been a known issue since 6/2020 -- that is three and a half years!
