Creating reports and dashboards | Stimulsoft community forum

Hi,
I have columns with sorted intervals and rows with services,
Cross-summaries are "amount to pay" and "paid amount".
I would like to add one more cumulative cross-summary "debt",
which will show value = "debt" for prior intervals + "amount to pay" - "paid amount";
How can I do it with StimulReports?
I tried use variables, but I did not found component events to manage them.
Regards,
Anton

Unfortunately this is unsupported feature in the current version of the CrossTab component.

Thank you.
