Hello @ DLS
Thank you for posting in the Community though I am sorry that you are experiencing this issue with the year end copy. The process and specifics that you have described indicate that the transactions prior to 1/1/2014 should not be included in the current file. You’ve done it exactly right. I’ll just include a couple of screenshots to be sure that you are seeing the correct popup options in the product.
Here is the first window, you'll choose the 2nd option "I only want transactions in my current data file starting with this date:" There you'll choose the date 01/01/2014
The date field on the bottom should auto populate with the date 12/31/2013.
