The No. of User Assignments field on the evaluation card shows the number of users who have added the evaluation to their My Excel Evaluations list.
For more information, see Execute Evaluations, My Excel Evaluations.
Click on the field to manage or change the assignments.
Basically, users can add an evaluation to their My Excel Evaluations list by themselves if they are allowed to execute the evaluation.
However, it is also possible to add an evaluation to the My Excel Evaluations list of certain users via the user assignments.
Note
User Assignments have no influence on whether a user is allowed to execute an evaluation or not.
The permissions for execution are only set via the User Permissions.
For more information, see Edit Evaluations, Extended, User Permissions.
If the user permissions are changed, the evaluation may be assigned to users who no longer have permission to execute the evaluation.
