The following query finds all the responsibilities that are assigned to a user. This query can be useful if you want to know if a user has a particular responsibility or any responsibility that has been end dated. However, if you just want to see the current "Active" responsibilities of the user, uncomment the "FURG.END_DATE" condition (very bottom line of the query).
In the following example, I used "AMOHSIN" as my user name to list all my responsibilities.
