Diagnosis
The register is relevant to billing on the specified date, but no meterreading result is allocated to the billing order. This means that it isnot possible to determine the end of the billing period.

System Response

Procedure
The cause of the problem may be as follows:

• If the device/register was not relevant to billing on the
scheduled meter reading date, it is possible that it was not taken intoaccount during meter reading data entry. By entering the meter readingresults for other registers, you determine the end of the billingperiod from the meter reading date of those registers.

• If a device or register is actually relevant to billing on this
meter reading date, then you require a periodic meter reading result,which you may need to provide subsequently.
If neither of these cases apply, the problem could be due to aninternal error, and you should contact SAP.
