Hi,
I can understand that payroll function has a abap code attached to it,
when we open schema using pe01, we can see the function being called, then rule called after that.
And rule has operations which has code attached to it.
Now I am not able to understand how the abap code of funtion calls the rule and how the processig is done.
In short, how data is flowed between functions, rules and operations.
Regards,
Manu
