Hi Porto,
Both these Function modules are called inside the FM:
"ISU_TRIGGER_BILLING_EXECUTE" based out of some conditions (I'll come to this later)
But first defferentiation on these 2:
1. It works on the simulation mode as it's not expected that EABL contains all the meter reading of all the meters, so a simulation is carried out.
2. It works on the exact meter readings in table EABL.
Now as promised , coming to the conditions of calling this:
Now the first one gets called when
"Billing Does Not Estimate Value Deleted by Individual Report"
In all the rest cases
Billing Estimates Value from Meter Reading Unit
Billing Estimates Value Changed by Mass Report
Billing Estimates Value Changed by Individual Report
The second FM is used.
I hope this will help.
Best regards,
Amit
