Auto step increment in salary struture

How can i implement a salary structure that will automatically increment an employee from level 1/1 to level 1/2,level 1/3…
The increment will be done every year.

You can create Salary Structure based on levels. Update Employees in the Salary Structure based on their increment.

ok tanks… that means u update each employee manually every year…

Probabile you can write a custom script to automate user update based on your rules
