Hi! I'm new to openerp and i managed to install the nightly build rpm on an CenOS6. Thank you for the great project! Installation of several apps works without errors.

Now, i have one problem: I tried to install the mrp app on a new and freshly created database with no other apps installed. This leads to the error below.

Then i tried to install other apps before mrp. I was able to install almost all apps without any error. But trying to install mrp afterwards leads to the error again.

Due to another post here i tried to reinstall base packet. This does not fix the problem.

Can you tell me, how to install mrp app?

Error:

No such external ID currently defined in the system: resource.timesheet_group1
