in WRS, I try 'd like to make amount in cross-tabulation. One variable (C) is a composed variable : C= a/B defined in Info Map.
My problem is that for C variable, i don't want to have the sum in the amount but to realize the expression that compose the variable (A/B).
I have modified the aggregations properties in Info map but in WRS, i still have then sum like result and not then expression (A/B).
Have you tried to create a custom measure within the Web Report Studio report itself? I have a feeling that the difference between running it query time (information map) and running it post time (web report studio) is causing a hiccup in the ratio.
