Hello, 
I'm doing Crosstab report in report studio against relational database 
Rows. Date , SubSystem 
Columns: Department, Year, Desc 
Measure :Actual 
Prompt : Year, Month, Department. 
business logic for report is to find activity for actual $$ in selectedYear/selected month/dates and also  Prior months activity Balance Forward for  selected departments.
I could write calculation to find total, total( [actual] for [desc],[year],[system],[date]) as Dept total 
now how do i write condition or cal for getting running-total of [Depttotal]. 
here's calc for running-total i written.. 
running-total([depttotal] for [desc],[year],[department]) 
so how do I write a calc to get the running total even if system is having two records for single day? 
			
			
			
				I figured my self. all columns are defined as varchar or char data types on crosstab columns, so i have to change datatypes and redefine the grouping  in  new query subject in fm apply the determinants,  i guess it start.
 
thanks
