When setting up a TLR pay element you will need to add grades for each Payroll on the system.
Check the employee's Payroll
Go to the profile of the employee you need to add this TLR for.
Click the Payroll tab and then click Pay.
Check the name of the Payroll in the Pay Details section.
Check if this Payroll is added on the TLR pay element
Go to Setup and click Settings.
Select Module Settings.
Click Payroll Settings and then Pay Element.
Search for the TLR pay element and click it.
In the Grades section you will see the first column, called Payroll. If the employee's payroll is not added in this list, you will not see the TLR pay element when adding an addition to basic pay for them.
Click Add Grades.
Select the payroll, negotiating body, grades and pay scales and click Save.
Click Save.
Once the above has been completed, go back to the employee's profile and try adding the TLR again. You will now have the option in the dropdown list.
