I have a pivot table in which I have debits and credits. At the beginning of the year, there is a beginning balance of $600,000. I want to be able to see in the pivot by date how this total changes based on the debits and credits. In my expression for Running Total, I have the following: If (FACTTYPE = 'CHARGEOFF',600000- Sum(CHARGEOFFAMOUNT)). I also need to add when FACTTYPE = RECOVERY as well.
