How To Fix AH854 - Weighting key &1 temp. area &2 period &3 - &4: denominator is zero

AH854 - Overview

• Message type: E = Error

• Message class: AH - IS-U billing (master data)

• Message number: 854

• Message text: Weighting key &1 temp. area &2 period &3 - &4: denominator is zero

What causes this issue?

The total of the quotients (total of degree day coefficients /
conversion factor) overall the months of the interval is zero.
In this case, no weighted average of conversion factors can be
calculated in the gas billing, since this number is used in the
denominator in the relationship (total weight/total of quotients).

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Please check the degree day coefficient tables, as well as the gas
tables for calorific value and volume correction factor.
Usually, both the degree day coefficients and the conversion factors
must be positive, real numbers.
