I found out that the new Data Wrangling functionalities introduced in 7.11 https://community.tibco.com/wiki/whats-new-tibco-spotfire#toc-23 work only for analyses newly created in 7.11. But for analyses created e.g. in 7.8 that have been upgraded to 7.11 the functionality is not available. Actually I would very much like to have this feature also for "legacy" analyses.
Or to phrase this more generally: all data wrangling functionalities introduced in new versions should also be applicable to analyses created in an earlier version which has been migrated to a newer version.
This is incorrectly assigned to Jaspersoft. I don't know if you can change the product association. You may want to try to move or re-enter the request.
