Changing Report Variable reruns whole workflo

Hi,

I created a complex workflow and a report with workflow variable as report variable. When I change the report variable throu a combo list, the total workflow taking 5 minutes or more. The workflow variable is not used in the workflow but in the report to highlight the bar chart bar.

Thanks

Hi Brammen,
yes this is correct. And we cannot change this.

The problem is as we do not know if you use the workflow variable in the workflow we always need to reexecute the full workflow if it changes.

Cheers, Iris

Thank you. Are there any resources/whitepapers about performance improvments?
