Believe me, the problem with the Team resource is not the Assignment Owner
designation. Because you failed to specify a Default Assignment Owner value
for every human resource in your Enterprise Resource Pool, that is probably
the source of your problem. If you have assigned human resources to any
tasks in any project, you will have to apply the Task Update view, insert
the Assignment Owner column, and specify each human resource as his/her own
Assignment Owner in the project, and then republish the project. You will
only need to do this on existing projects. On future projects, the system
will set the Assignment Owner value as the one specified as the Default
Assignment Owner. Have you tried republishing the project to see if it
works now? Let us know.
