When submitting a report that will include data for more than 50,000 certificates, you see this error message:
The default maximum number of rows to include in a report is 50,000. This can be increased by adding a value for "Report Max Source Record Count" to the Reporting Object in on TPP server object in the Platforms tree. This is not available in the normal UI, so it must be added via the Support tab. This requires an edit key from Venafi Support. When you get the edit key, you can then add the needed value and set it to a number that is appropriate for your environment.
The example above shows a value of 200,000. Note that this is a per server setting, so you would need to make this change on all TPP servers that are going to generate reports that will have more than 50,000 elements included.
This attribute does not exist by default, and if not present, the default value (50000 rows) is used.
