Eliminate duplicates - Section Expert formula

I have a report with Section Expert formulas for some specific group/details results.

For further details, see this posted question:  http://scn.sap.com/thread/3885388

Briefly, my report is designed to include "ALL" notes from some staff people, but if those people did not create a note, then display "one" note from someone else.

This is working successfully.

However, I needed to add more criteria to the report which involves vouchers, so now I am getting some duplicate lines created because of a one-to-many relationship.

I tried changing join types, but believe I have this as "tweaked" as possible.

Is there a formula that can be created or edited, or some other way for me to not just "suppress" these (as some of these duplicates are creating dozens of lines), but to "eliminate the duplicates" caused by the one-to-many relationship the new voucher table is creating?

I have attached a "Fake" version of the report with saved data, if helpful.

Thanks for any help!
