How To Fix BM806 - Additive constant is usually only relevant for temperatures

SAP Error Message - Details

• Message type: E = Error

• Message class: BM - Development class BZME - units of measure

• Message number: 806

• Message text: Additive constant is usually only relevant for temperatures

What causes this issue?

When a unit was created, a value was entered in the field <LS>Additive
constant</>. It is usually only necessary to enter a value in this
field for a temperature. The unit here is not a unit of temperature.

System Response

The message is a warning.
If you continue processing, the value will be saved with the additive
constant.

How to fix this error?

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

• What is the cause and solution for SAP error message BM806 - Additive constant is usually only relevant for temperatures ?

  The SAP error message BM806, which states "Additive constant is usually only relevant for temperatures," typically occurs in the context of material master data or when working with certain calculations in SAP related to material properties, particularly in the area of chemical or process engineering.
  Cause:
  This error message is generally triggered when there is an attempt to use an additive constant in a context where it is not applicable. The additive constant is often used in calculations involving temperature-dependent properties, such as viscosity or density, and if it is applied in a scenario that does not involve temperature, SAP will raise this error.
  Solution:
  To resolve the BM806 error, consider the following steps:
  
  
  Check Material Master Data: Review the material master data for the specific material that is causing the error. Ensure that the additive constant is only defined for properties that are temperature-dependent.
  
  
  Review Calculation Settings: If you are performing calculations or using formulas that involve the additive constant, ensure that these calculations are appropriate for the context. If the calculation does not involve temperature, remove the additive constant from the formula.
  
  
  Adjust Configuration: If the error arises from a specific configuration or setting in SAP, you may need to adjust the configuration to ensure that additive constants are only applied in relevant scenarios.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly use additive constants in your specific context.
  
  
  Seek Expert Help: If the issue persists, consider reaching out to your SAP support team or a consultant who specializes in SAP material management or process engineering for further assistance.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context on how to handle additive constants.
  Material Types: Understand the different material types in SAP and how they relate to properties and calculations.
  Temperature-Dependent Properties: Familiarize yourself with how temperature affects various material properties and the role of additive constants in those calculations.
  
  By following these steps, you should be able to identify the root cause of the BM806 error and implement a suitable solution.
