They are on a fiscal year. 13 periods of 4 weeks each so not calendar months. I am not sure that is the issue because the first few item codes I looked at were displaying negative values.... exactly the opposite of what it should be. For example, I created a Crystal report using the AR history tables and the amount for period 1 of 2016 should be $18,455. The Sales History report was showing negative $-18,455. Other values are nonsensical.... Should be $38,345 and showing $53,250. Looking at the detailed transaction non of the numbers in the date range come anywhere close.
