Pull text data from one column, based on multiple criteria

Thanks for a quick response Ashish, you provided some good insight in general; however, using your file I made a few updates to better illustrate my probem.  

1. I didn't mention that I need the information to display in a matrix similar to what is shown below.
2. With the new example, the result I would want under the "Last interaction details" column is "aaa", becuase this is the information associated with the last time a violation was identified (As you can see with the current measure the column is pulling "bbb" which is associated with the latest audit date in general).

Let me know if this explanation is clear and if this can be done. Thanks again!
