Hi, We have a strong requirement to log data exports by PDF or Excel from user-executed report definitions. I have seen a previous question Export to Excel - Log Functionality but this suggests using the built-in logging. Trouble is that the built-in logging is just gives you this (test on 8.6.4 but on 8.8.3 next month):  

2023-09-06 11:44:59,386 [http-nio-8080-exec-1] [  STANDARD] [ ] [APPP:45.00] (e_Obj_Report_Definition.Action) DEBUG ourmachine.pegacloud.net|X.X.X.X MYNODE richard - Running step 1_circum0 2023-09-06 11:44:59,387 [http-nio-8080-exec-1] [  STANDARD] [ ] [APPP:45.00] (e_Obj_Report_Definition.Action) DEBUG ourmachine.pegacloud.net|X.X.X.X MYNODE richard - Show method output is NOT suppressed.

Based on this logging:

There are no extension points and ALL of the rules in report execution and export are final (makes me nostalgic for PRPC 5 where you could write your own report activity). If you've found a solution I would love to hear from you!
