Negative consumption

Former Member

Hello experts,

We have a real problem with negative consumption.

We are not able to enter a meter reading lower than the last meter reading.

In that case we would like that SAP calculate a negative consumption.

But it seems impossible.

We get a register overflow.

For example :

Last meter reading : 4000 kWh

New meter reading : 3950 kWh

(Max register 9999 kWh)

We expected a consumption of -50 kwh but the consumption calculated is 3950+5999= 9949 kWh

Is it a customizing problem ?

How can we enter meter reading with a negative consumption calculated and how can we invoice negative consumption ?

It could be very nice if someone could help you to solve our issue.

Implement the Event to check the Limit : R924 Event.

Minimum Charge/Amount Limit for BB :: Table TE557.

You can check the negative consumption in this event Pls have a look at the function module documentation you will have a good idea.

Thank you Shiva for your quick answer.

We look at event R924 and we could probably solve our billing problem with it.

Now, we need to solve our meter reading problem.

Look at the event R974.

use this FM :: ISU_SAMPLE_R974

if negative consumption is there then populate the field :: y_min_failed = 'X'.
