I am pretty sure that FlexPLM is built on top of Windchill. Therefore, the PLM number for the trim is probably modeled like a part, and the styles are probably modeled like a bill of material. If that is even remotely true, then on the details page of the trim PLM number there is probably a "Structure" tab, or something similar. I suspect that you can get what you are looking for from one of the out of the box Reports on the structure page if you cannot simply use the structure tab to get what you want. On the other hand, if the styles are more like documents or something else, then you might find what you want on the "Related Objects" tab (if there is one) from the PLM number details page. These are wild guesses, so if anyone knows any better please explain. I've never actually seen Flex PLM.
Here are some more wild guesses to your other questions.
"What are the limitations of adapting the current data management within Flex PLM? How flexible is the user interface of Flex PLM?"
If you can find the FlexPLM equivalent of the structure tab, mentioned above, then you can edit that display to show, hide, or reorder columns; you can modify the filter to show the bill of material (BOM) you are looking at; and you can make custom filters and save them for reuse. You can also most likely click the "+" at the top of the Details page for an object to create a personalized tab of information that you add from the "Customize" pull down, if that is exposed in FlexPLM like it is in PDMLink. You can probably do something like an Advanced Search where you can create personalized "Saved Searches." And somewhere in there is probably Query Builder for admins to build custom reports.
I think the main thing is to try to think like Windchill to find what you want. Everything, like a PLM Number, is an "object." Objects have relationships to other objects. Those relationships are always shown from one of the tabs or links from the main details page of any object. Anything with multiple levels of indenture in their relationships is typically called a "structure" of some kind. Anything that just links one thing to another is typically called "related" or "reference" or something similar. When in doubt about what you are looking at, then go to the on-line help from any "?" you see, which is typically context sensitive; or else go to the main help (typically in a pull down from the top right of the page) and search for something you are interested in learning about.
