This situation indicates that the Project Server administrator did not
specify a Default Assignment Owner value for this resource in PWA. He/she
can do so from the Resource Center page by selecting the checkbox for this
resource and then clicking the Edit Details button. Click the Browse button
to the right of the Default Assignment Owner field and then select the
resource in question from the pick list, and finally click the Save button.
Next, the PM of the project must manually specify an Assignment Owner value
for every task assigned to this resource in the project. To do this, the PM
should open the project and apply the Resource Usage view. He/she should
right click on the first column to the right of the Resource Name column,
and on the shortcut menu, select the "Insert Column" item on the list. In
the Field Definition dialog, select the Assignment Owner field and then
click the OK button. For each task assigned to this resource, the PM should
select the resource's own name in the Assignment Owner field. The PM should
then save and publish the project. The tasks assigned to this resource
should now appear on the resource's My Tasks page in PWA.
Hope this helps.
