    What are you going to do when you hit Z?  Loop back to AA?   Off the top of my head.. Create an invoice suffix table.. Prepopulate row by row A - Z, AA - ZZ..... as you use them.. mark them used ...  to find the first unused.. use a first with the select ... something like. 

    first(select('Inovice Suffix')[Used=null])

    thank you, that is my option for now. I hope this can be a feature embedded in NX.

    regards
