Client and Matter Exception Rates

Client and matter exception rates are one of the more difficult areas to manage in Enterprise. This can be complicated by the fact in versions prior to 3.10, there is no end date on the records. In order to end an exception, you had to enter a new line with a zero percent or dollar deviation. Thankfully this has been corrected in 3.10. For those still on prior versions, this bit of code gives you a full view of exceptions for clients and matters. In an effort to make the data a bit more manageable, there is a department variable that limits the results of the query to a single department.

This is probably as good a time as any to point out the merits (and limitations) of common table expressions (CTE) as opposed to sub-queries. You can see in the top portion of the query below that there is a "WITH" expression. Using a WITH expression creates a common table expression from a query and gives it a name, in this case maxmex. You can then call this CTE later in your query as if it were a table. However, note in the client section that I've used subqueries instead of a CTE. WITH expressions can only be used at the beginning of a query, and a previous query/statement must be ended with a semicolon before a WITH expression can be used. Since the UNION ALL is a continuation of the query, we can't use a WITH at that point. However, in my opinion, CTEs are much easier to read and understand than sub-queries, so I highly recommend their use.
