Client, Gotta love them! Without them, I would be handing out carts at Wal-mart. I am not one to throw things out (it KILLED me the other day when I found the Mr. Coffee in the trash bin) so I rarely suggest purging history files. As long as file space remains inexpensive and performance is not an issue, I just let them build. Running the PE processing isn't as critical as it once was, but it does purge the open AR and AP invoice tables. Occasionally, I will purge zero tier cost tables as well.
