How To Fix AJ183 - Cal. value maintenance not permitted for CV procedure &1 time ref. CV &2

SAP Error Message - Details

• Message type: E = Error

• Message class: AJ - Billing program

• Message number: 183

• Message text: Cal. value maintenance not permitted for CV procedure &1 time ref. CV &2

What causes this issue?

Calorific value maintenance only allows you to maintain month-specific
calorific values. A calorific value procedure in which the time
reference is 1 day cannot be used. In this case, the actual billing
calorific values are not defined in calorific value maintenance. In
this case, the billing calorific values are determined directly during
billing (e.g. arithmetic average over the billing period).

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?

If daily calorific values are involved, you only have to enter the
values in the table of calorific values per calorific value district
(daily values).
In the corresponding calorific value procedure, you can define the
exact operation for billing for this table like the arithmetic average
formation.
