Yes, All of my forms (except one or two) are with private Data session. Also I never use a Data Environment in the reports. I prepare the cursor that I want to print before the report and then just run the report based on that cursor. That gives you a possibility to use one report for many different data sets and completely different information. I use ONE report to print all my nomenclatures ( I don't know the exact words for this type of tables on English).
