• What is the cause and solution for SAP error message VCH_L2A_CHECKS124 - The usage of non-model characteristics is not supported ?

  The SAP error message VCH_L2A_CHECKS124 indicates that there is an issue with the usage of non-model characteristics in a specific context, typically related to the configuration of a variant configuration model. This error often arises when trying to create or process a variant configuration that includes characteristics that are not defined as model characteristics.
  Cause:
  
  Non-Model Characteristics: The error occurs when you attempt to use characteristics that are not defined as part of the model in a variant configuration scenario. In SAP, model characteristics are those that are explicitly defined in the configuration model, while non-model characteristics are not.
  Incorrect Configuration: The configuration of the product or variant may not be set up correctly, leading to the inclusion of characteristics that are not allowed in the context of the model.
  Data Inconsistency: There may be inconsistencies in the data or configuration settings that lead to the system not recognizing certain characteristics as valid for the model.
  
  Solution:
  
  Check Model Characteristics: Review the configuration model to ensure that all characteristics being used are defined as model characteristics. You can do this by navigating to the configuration model in the SAP system and checking the characteristics assigned to it.
  Adjust Configuration: If you find that certain characteristics are not part of the model, you may need to either:
  
  Add them to the model as model characteristics.
  Remove them from the configuration process if they are not needed.
  
  
  Review Dependencies: Check for any dependencies or constraints that may be affecting the characteristics. Ensure that all dependencies are correctly defined and that they do not reference non-model characteristics.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on configuring variant models and characteristics. This can provide insights into best practices and common pitfalls.
  Testing: After making changes, test the configuration to ensure that the error does not reoccur and that the variant configuration works as expected.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CU01 (Create Configuration Profile), CU02 (Change Configuration Profile), and CU03 (Display Configuration Profile) to manage characteristics and models.
  Variant Configuration: Understanding the principles of variant configuration in SAP can help in troubleshooting and resolving issues related to characteristics and models.
  
  If the issue persists after following these steps, it may be beneficial to consult with an SAP expert or support team for further assistance.
