Why can I not move project that is state: In Progress to the state: On Hold in Madrid?

[jbugarin]

In the instance that we use, I am trying to switch my progress from the state In Progress to On Hold. The error I am receving is this: "Updating project state from Work In Progress to Pending or Open is not allowed. Update all tasks state to Open to set project state to Open. " 

Is there a different way to get around this issue besides having to set all the task to open which resets all to 0 percent. 

Thanks

So you are saying that if I have a project with 5 tasks and 2 of those tasks are complete but the others are in progress or on hold for whatever reason I cannot switch the project state to pending?

I don't really understand why a project, with partial task already closed (so with an existing progression), cannot be changed to Pending without replacing all the earlier closed task to pending. It 's not a normal way to place a partial executed project to a pending (on-Hold) state. What about the global realization %? If I change all the closed task to pending, my project is back to 0% of realization. That's not a proper way to manage it...

Pending should inform that the project is waiting about something and nothing is work in progress. But the already closed tasks should remain closed!
