System Response

How to fix this error?

The cause of the problem may be as follows:
If the device/register was <ZH>not relevant to billing</> on the
scheduled meter reading date, it is possible that it was not taken into
account during meter reading data entry. By entering the meter reading
results for other registers, you determine the end of the billing
period from the meter reading date of those registers.
If a device or register is actually <ZH>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 an
internal error, and you should contact SAP.
