In most cases, ss long as the employees are active and have not been filtered out, a time sheet should be produced. If this does not happen, complete a re org with File Maintenance of the Payroll files as the first step.
NOTE: In the File Name/Mask field, enter ##py* where ## is your division number.
Depending on the client setup, there are other reasons that not all employees will pull to group timesheets.
An earning item may have been selected that does not apply to all employees, especially when the Payroll Parameter is set up to use departmentalization. Go to Payroll/Personnel, Setup, Payroll Parameter. Note all the options selected in field 1, as they all have effects on how the employees are set up and how group timesheets are pulled. DO NOT CHANGE THESE OPTIONS as they control the way your payroll system should work.
When calling Support for further troubleshooting steps, your analyst will need to know what is in your parameter, and what earning item you are using to pull into group timesheets.
