Hello. I have a such quastion.
I need to bill some consumer. There is two ways to bill:
1. Meter reading results are entered. In this way we have some price and multiply this with consumption. Using Rate.
2. Meter reading results are not entered. In this case we have some other algorithm. How and where should I do customizing to use this algorithm?
So I need:
IF meter reading results are entered it bills using first way.
IF meter reading results are not entered in bills using second way.
