Calculate percentage of total columns based on total column in SSRS Matrix
Looking to add a column in my SSRS Matrix which will give me the percentage from the total column in that row. I'm using the following expression, but keep getting 100% for my percentages (I'm assuming this is because the total is evaluated last, so it's just doing Total/Total? =FORMAT((Fields!ID.Value/SUM(Fields!ID.Value)), "P") The field ID is calcuted within SQL, not SSRS. For example Site | Value 1 | %1 | Value2 | %2 | Total 1 | 20 | 50% | 20 | 50% | 40 Probably this is happening because you need define the right scope for the SUM function: SUM(Fields!ID.Value,"group_name") instead of
