Project Online overwriting my calendar when uploading

Hi

I hope someone can help

I am having an issue when uploading a new project from the desktop to project online.

The main base calendar for the system does not have any exceptions, as we are a global company and projects arent limited to one region it has been decided that we should ask the project managers to manually review national holiday exceptions and manually push tasks out rather than building the system to cover all potential holidays.

As is always the case, the issue I am having is a project which is an exception to the above rule. The project in question has a different base calendar which accounts for national holidays in one region. As this is a one off, and the project is very detailed and old, I would like to just upload it as is.

So:

• I have created a copy of the regional calendar and added it as an enterprise calendar in the system
• Prior to using the import wizard, I have changed the project calendar and working time calendar to the new base
• when using the import wizard I have checked at each stage to ensure the working calendar has not changed
• I have changed the resources calendar to the new base

The above ensures no tasks are assigned during the exemption period, Ive checked at each stage of the wizard and this approach is working

Then it goes wrong, as soon as you select save (in the wizard) the task dates all move so some are scheduled where there should be an exception i.e. it seems to adopt the standard base calendar, this is for tasks with and without resources assigned. The region specific calendar is still displaying in the working time box so I am not sure what is going wrong

 Id be grateful if someone could help with this

Thanks

Matt
