• What is the cause and solution for SAP error message AXT_MODEL258 - Rule handler only supports BOL entities ?

  The SAP error message AXT_MODEL258, which states "Rule handler only supports BOL entities," typically occurs in the context of SAP's Business Object Layer (BOL) when working with the SAP CRM (Customer Relationship Management) system. This error indicates that a rule handler is being invoked for an entity that is not a BOL entity, which is required for the operation to proceed.
  Cause:
  
  Incorrect Entity Type: The most common cause of this error is that the operation or rule handler is being applied to a non-BOL entity. BOL entities are specific objects that are part of the Business Object Layer in SAP CRM, and the rule handler is designed to work only with these entities.

  Solution:
  
  Check Entity Type: Ensure that the entity you are working with is indeed a BOL entity. You can do this by reviewing the entity definitions in the BOL model.
  Review Rule Handlers: If you are using custom rule handlers, verify that they are designed to handle only BOL entities. You may need to modify the logic to ensure that it checks the entity type before processing.
  Debugging: Use debugging tools to trace the execution flow and identify where the error is being triggered. This can help pinpoint the exact location in the code or configuration that is causing the issue.
  Consult Documentation: Refer to SAP documentation for the specific version of your CRM system to understand the expected behavior of the rule handlers and BOL entities.
