I have a field, transDATE, representative of the transaction date. I have a field [Net Sold Qty] representative of the number of tickets sold.
I want to create a column within a table that shows the previous day sales. So if today, I have 10,000 tickets sold, but yesterday, I had 9,900 tickets sold, i want to be able to show that there were 100 tickets sold.
Would I set this up in the script or in an expression? What would this look like?
