Organization timesheet is only available if you have JIRA Service Desk.
In latest version of JIRA Service Desk you can group your customers into organizations. Using 'Custom Timesheet' feature of WorkLogPRO you can easily create timesheet reports all the issues reported by member of a selected organization.
Creating organization timesheet is very similar to other timesheets. Open 'Custom Timesheet' from WorklogPRO main menu and select Organization for 'Timesheet Type' and write the name of organization.
Functionality of the organization timesheet is the same with other timesheets.
