Configure Lunch Allowance

Hi,

I have this situation: my client has two values to lunch allowance (value X is used all week, and the value Y is used when the employee works on Saturdays).

I already set and process the lunch allowance with the value X and itu2019s ok.

But I have no idea how to set and process the lunch allowance value Y.

If you could help me, I would be appreciate that.

Thank you,

ST
