Recently, I've found an unknown origin value in ReportEvent logs. The documentation is inexhaustive on the subject.

According to all Salesforce documentations, the ProbeQuery event report type origin correspond to a "report executed from a probe query". However, nowhere is stated what is a probe query in Salesforce.

This question was also asked on Trailblazer Community and Salesforce Developer group with no answers.


  • I see a support case logged for this scenario which is in progress. I will update this thread as I have more information. Thank you --Salesforce Support Jan 25, 2021 at 14:51

According to the support case I've opened, a probe query is a search query used to retrieve column text values and search terms for text bucketing. It is executed by the user when he or she uses the report builder.
