MOM SCDWgroom Enhancement

,

It might not be useful now, but if you ever wanted to downsize the amount of data that you keep in your datawarehouse, good luck.  This will help you do that.  This job is set to shrink it down to 120 days, but you can adjust it as you like.  Runs again in 5 day increments with each run.
