Iterate Arraylist

[victor_33]

I have a report that i would like to iterate a arraylist. The arraylist is a parameter, i found that i can use it as a datasource for a subreport, but i need to compare the values of the array with values of a query and make some calculations. And show it on the detail as rows. Example:

Array values    Query values   Result

10                     10                    0

10                     20                    10

30                    10                    -20

 

How can i do this ?

If your datasource is the result of the query, you can use the parameter REPORT_COUNT as index and get the respective value from the colection and make the calculations.
