Hi Tim - Accsys Consulting 

thank your for the write ups. That’s exactly what I faced step by step. I even tried commenting out the datapipes to use report I think it’s OEINV02. The issue was with sub reports. It kept throwing the parameters screen when trying to print on classic

when I commented out I could tell the BOMs and Lot/Serial numbers sub reports were the ones throwing parameter pop ups on classic.

 I'm not sure if there is a separate oerpt.ini equivalent for sub reports.

Hi Mr_Mayor the subreports aren't datapipes so I don't think they will have an INI file (I could be wrong).  Good thinking though, you might be able to solve it by placing the optional field in a subreport and carefully working it into where you need it to display (I know this can be very painful to get cosmetically right but likely a better option than placing it in the main report).  Otherwise if you really want the Optional Field in the main report, making CSCOM an active part of the joins might work however I suspect you will need to use OE Invoice 03 to 05.  Good luck and keep us updated.
