After the installation of Reporting Service, only the data for the main tenant is captured in the database.
By default, the capturing of data is enabled for the main tenant only.
In order for other tenants' data to be captured by the Reporting Service, there is a modification required to the FlexiCapture database. Set Flags to '1' for the tenants that you'd like to be processed by the Reporting Service in the dbo.Tenant table.
A database backup is recommended before proceeding with the modification.
