Hi All,

I hope someone is able to help me with a SQL that I am trying to build. I have several reports that require the same information so I am trying to build a generic query that we can use for different reports but I am having troubles with getting the query to do what I want.

I want to be able to have Assignment ID, Person ID, assignment status, effective start date, action name and action reason 

the effective date and the action information should be from when the assignment status changed
