We seem to have some issues with the reports, where selecting a field for the summation, a field which exists with the same name in two different phases, leads to the field being selected twice (for the sum).
This is not ok; it’s not even clear which of the two fields is finally used for the sum.
On a side note: it would make sense to have the same list of fields (particularly including the phases as subtitles) in the list of fields to use for the sum as in the list of fields to use for columns.
Changing all fields to have different names is not an acceptable solution (though a workaround for now); we have many pipes with many duplicate fields (reason: one field for each article to input in the one phase how many of this article to list in the offer, and then in a later phase, how many of these articles to charge/invoice).
I’m facing the same issue!
