I have a question about using Group by in PEGA, acttually two questions:
1. What is suggested approach for implementing "group by" functionality in PEGA for reports or data pages?
2. I need to implement a "group by" functionality. I'm using a report and Summarize option in "Edit columns" section. Putting this report in a repeat grid and not able to save repeat grid section, getting error message:<cell property> is not a valid Report-Definition Field. pyRDName: Summary type Report-Definition are not supported for Repeating Grid.
