Roadmaps - a functionality available in CA PPM versions 15.4 and above - have a feature to define individual Items within them. Each of these Items can be provided a title with a maximum of 80 characters. However, if the title of an Item is longer than the time span of an Item, then there is no text wrapping that occurs. The titles are not truncated within the limits of an Item's span either. A screenshot to better show this scenario is provided below.
CA PPM 15.4 and 15.4 (SP 1).
This is working as designed for the versions mentioned above. However, the Product Engineering team is looking into enhancing this functionality in a future release.
Please limit a Roadmap Item's title to within the bounds of that particular Item's span, on the Swim Lane of a Roadmap.
