• Message type: E = Error

• Message class: O3 - IS-Oil: HPM messages (goods movements, QCI, deliveries)

• Message number: 138

• Message text: Coefficient and fixed density/gravity only allowed for chemicals

What causes this issue?

You attempted to enter a thermal expansion coefficient (quantity
conversion coefficient) and/or a fixed density for a material that has
been assigned to a non-chemical conversion group.

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?

Change the conversion group of the material to a chemical conversion

• What is the cause and solution for SAP error message O3138 - Coefficient and fixed density/gravity only allowed for chemicals ?

  The SAP error message O3138 indicates that there is an issue with the configuration of materials in the system, specifically related to the density or gravity settings for materials that are not classified as chemicals. This error typically arises when you attempt to assign a coefficient or fixed density/gravity to a material that is not categorized as a chemical substance in the SAP system.
  
  Cause:
  
  Material Classification: The material you are trying to configure is not classified as a chemical. In SAP, certain properties like density or gravity are only applicable to materials that are classified as chemicals.
  Incorrect Data Entry: There may be incorrect data entries in the material master record, particularly in the classification or basic data views.
  Configuration Settings: The system settings or configuration may not allow for the assignment of density/gravity to non-chemical materials.
  
  
  Solution:
  
  
  Check Material Classification:
  
  Verify the classification of the material in the material master. Ensure that it is classified
