I am attempting to define a report that will automatically print three copies of a delivery note, one for us, one for the customer and one for the courier.

Ideally, I'd like the pages to display text describing which copy it is.

Since all copies are virtually identical, I had thought of using a sub-report and calling it with a comma separated list such as "1,2,3" - maybe within the subreport, I could then split this list into the distinct values and set these as a group. Partially formed thought... don't know the practicality of this approach.

Now solved.

The issue with the linked parameter was because I was trying to explicitly pass the parameters to the subreport.

But as the subreport used to be the master report, it already had params of the same name so I could leave the link as implied only.

I also had issues with the pagination as I was trying to force breaks before each details section this interfered with the forced page break after the page footer, sometimes putting in two. I resolved this by making the subreport too big for more than one to appear on a page, forcing clean breaks.
