I have the following data and I am creating a pivot table using SSRS with row group and column group. I am having to find difference between the values in the column. I want the report to run based on the time range so the column might
increase or decrease. The only thing i can add in SSRS is a total sum column but not difference. How do I create a column that gives me the difference? Please help. The pivot structure is below the data.... Thank you.
