Problems printing "n" copies of a report

Hello everyone,

I have created a new report, using “Assembly Header” and “Item” tables. When I only create one copy of the report, everything runs OK. But he isues come when I create more than one copy. I’ve used as “inspiration” this article:


The structure in the object designer is this one:


And the properties at “Item” are the next ones:


When, for exampple, I try to make 2 copies (with request page), NAV repeats twice just the “Assembly Header.No.” value, no the others. I think that the issue can be about sorting or grouping the keys, but I’ve tried differente options without expected result. Any clues with this??

Thank you very much, and merry christmas for every one!
