Need a table name which stores Attribute2 parameter values, Normally the request details can be found in ess_request_history table. But I am unable to find the table which stores the parameter values while scheduling the particular program.

Please find attachment for your reference. We need to validate period_name with the process once we have the table name which stores this data.

Please help accordingly.

Thanks,
