Negative consumption

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.

      Look at the event R974.

      use this FM :: ISU_SAMPLE_R974

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