Additional Salary

I’m using Additional Salary and i couldn’t understand it.
I can add a new component to an employee and I can set a fixed value for him.

But If “add” an existing component, overriding it or not, every other component that references the first one does not change.

Component Salary = 5000 (earning)
Component Tax = Salary * 0.05 (deduction) → 250

after adding an additional salary :
Component Salary = 6000
Component Tax = Salary * 0.05 → 250

So, it looks like the additional salary it is been added after the salary structure calculations. My goal here was to add an additional salary base on the original salary, like a percentage increment.

Any help on that?

Did you ever get this figured out? I’m facing a similar problem.
