The document discusses how to configure an SAP system to estimate meter readings for a contract using either periodic consumption or extrapolation based on past readings. It provides screenshots showing how to set up a business add-in (BAdi) implementation to toggle between periodic consumption and extrapolation estimates for meter readings. Activating or deactivating the BAdi implementation determines whether meter readings are estimated using periodic consumption or extrapolation.

1. Extrapolation with Periodic
Consumption
Recently a query was raised in SDN. http://scn.sap.com/thread/3289705
Have pasted it below for followup.
Query in SDN
This was an interesting learning as I didn't have any idea that we had such an option available. :)
Below screenshots and subsequent text show how it works. Probably it shall help others (as it helped me)
as would the SDN post in getting clarification on how this is done.

2. The BAdi is ‘ISU_USE_EASTE’. Method is ‘USE_EASTE’. Use transaction SE18 to check this.
BAdi ISU_USE_EASTE
Use Transaction SE19 to create an implementation for the above BAdi.
BAdi Implementation
Use Transaction SE24 to open the implementation class.

3. SE24 : Class Builder
Enter the following code in the method ‘USE_EASTE’.
Code in the Method
Activate everything now. Now let’s check with a master data. The Contract is a new one, so the first meter
reading would anyways be a ‘periodic consumption’.
Move-In on 01012011
First Reading estimate.

4. First Meter Reading
Now the second reading estimate.
Second Meter Reading
So for the second reading also it estimates based on periodic consumption. Now I have
deactivated the Implementation.

5. Implementation not Active
Let’s check again. First reading would anyways be ‘periodic consumption’.
First Meter Reading
Now lets the check the second reading.

6. Second Meter Reading
So with the Implementation deactivated, the meter reading is extrapolated with the past meter reading
results. So the BAdi works.
I think we can try many things in here. Again interesting learning. :)
Anyways credit to people involved in the SDN post, no copyright infringement intended from my side. :)
