Full Use Case:
When I generate my document to print name label for 3 separate contacts (from 3 separate related list merge fields into one table on one record), the names are merging but it’s printing them 3 times instead of once. Why is that happening and how to resolve?
RS Documents app only merge related lists with one record per row, and not repeating horizontal. Conga might be able to solve your use case. We could consider adding a feature to support this for a fee, if you are interested then contact firstname.lastname@example.org.
