There is an option for "Insert Filter Text". See screenshot.

This gives you a text object you can put anywhere in your report. I have put it in the header.

This is dynamic if using the basic filter functionality. In its default state against a data module report it is pretty ugly:

But if you edit the data item to remove the path:

It looks a lot nicer:

I have flagged up this bug to IBM.
I always recommend that anyone who write reports against data modules removes the path from any expression for two reasons:
- It makes the filter text understandable to the user
- I can repoint the report to a different data module that has the same queries and it still works
I found this feature out when using creating a report against a data module that has standalone calculations. When you add these calculations to a report it doesn't include the path in the expression so I have no idea why the report editor sometimes includes the path to make things worse.
Add more filters and the filter text expands. It also works in the interactive viewer.

It will only explain filters that are added using the filter interface. If you add a filter directly to the query you may see something like this:

But its good enough for 90% of my ex QS users.
