Dear Aldo:
While the export tool is supported, there has not been a public update since 9.1 (November 2010). So while you can open a case, I am not sure what changes will be made. I am interested on the report that you ran
I see you are running report 23
23: Get aggregated business process (business service) statistics data for a specified business process (business service) in a time range.
This command returns only one row of data for the specified business process (business service) in the given time range.
This can be done with the Export Data Tab in the MOM GUI. You do not need to be a CEM Admin to run this. See Export Data - CA Application Performance Management - 10.7 - CA Technologies Documentation for details. Please try this and see if it can meet your needs
