Reporting Error in WCS 7.0.172.0

[rubleinda]

Runing the report, "CleanAir > Worst Interferers" and I get this error

The specified criteria did not match any data for the report.

Make sure that the following background tasks are running:

1. Interferers

I know there is data that should match up because I can see it on the individual controllers.

I checked the background task Interferers and it appears to be working as well but just to make sure I forced the "Execute Now" command but the report still failed.

Has anyone else seen this?

Do you have a MSE?

[rubleinda]

No, we do not have MSE.

[BRYN JONES]

We are getting this and I am also perplexed as to what needs doing, as all my settings appear correct and I cannot find 'Interferers' as an item in the Background Tasks

I opened a TAC case, according to Cisco the clean air feature requires a Plus/Location license to be installed on the WCS
