I designed an SSRS report which has a table that has a numeric column. The table can span over multiple pages. In the table footer I ams showing the total sum for all values of this column, and I am showing this footer on each page of the report. However, I need this total at the end of each page to be a running total - ie it should only show the sum of all values from the beginning of the table (ie the beginning of the report) up to the footer itself. How can this be approached?
