Using alias attributes it is possible to display information from related objects in info pages and (from 10.1 M040) table views.
One use-case is to create an alias atribute on the workitem object that retrives the related ECN or ECR. The alias attribute can then be added to
the task table on the homepage for easy viewing.
Alias attributes also supports one-to-many relations. An example of this is retriving the name of the user that has completed a task of a related promotion request for a WTPart (or other promotable object). Using the ootb promtion approval process there is both an approval task and a review task.
The alias attribut will in this case show two user names(comma separated), one from the approval task and one from the review task.
If only the name of the user for the approval task is wanted there is no way to solve this today. It should be able to add a filter criteria to the alias attribute mapping. In the above exampel a filter on the name (name = "Approve Promotion Request") of the task would solve the use-case.
