The Only Annualized Salary field in Definitiv's Micropay Integration determines which employees from MicrOpay will appear in Definitiv.
Tick this field if you only want employees from MicrOpay who have Yes selected for Annualised Salary in Annualised Salary on their employee record. This will bring across just the annualised salary or wage assurance employees.
Untick this field if you want all employees from MicrOpay. You would untick this if, for example, you are using Definitiv as your Employee Self-Sevice (ESS) platform.
