I have a crosstab in BO Webi XIR3 (2years of data by division); 1st level is fiscal year, 2nd level is Org: values A, B, C for current fiscal year and fiscal year+1. I am showing $ as a measure and now want to add in a Difference at the end of the crosstab to calculate the delta between the year/org combinations. The result appears like an extension to the crosstab (see attached), a 3rd set of columns. Can I do this in Webi and how is it set up? Otherwise I'll just have the user export to excel and add the delta there as a formula if I have to. Any ideas, I'm just not seeing it? Thanks.
