SAP Error Message - Details

• Message type: E = Error

• Message class: MR - Stock overview for generic materials

• Message number: 023

• Message text: No variant-creating characteristics could be determined for class &

What causes this issue?

No characteristics could be determined with the attribute
"variant-creating" for the class entered (generic material or material
group).
In material group hierarchy maintenance, you can flag a characteristic
as variant-creating if, when assigning the characteristic to the
material group/material group hierarchy level or to the generic
material, you set the usage indicator accordingly.

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?

Set the usage indicator for two characteristic assignments at most.
If variant-creating characteristics have already been assigned, but
were not found, this may be because you have not entered a material
group within the hierarchy for which the variant-creating
characteristics are known. Try choosing a lower material group level.

This error indicates that the system is unable to find any characteristics that can be used to create a variant for the specified class.
  Cause:
  
  Missing Characteristics: The class specified in the error message does not have any characteristics defined that can be used for variant configuration.
  Incorrect Class Assignment: The material or object you are trying to configure may not be correctly assigned to the class that has variant characteristics.
  Configuration Profile Issues: The configuration profile for the material may not be set up correctly, or it may not be linked to the appropriate class.
  Class Type: The class type used may not be suitable for variant configuration. For example, it should be a class type that supports variant configuration (e.g., class type 300).
  Authorization Issues: There may be authorization issues preventing the system from accessing the characteristics of the class.
