  Improperly Defined Enhancements: Enhancements that are not clearly defined or that overlap in functionality can lead to this error.
  
  Solution:
  
  Review Enhancements: Check all enhancements applied to the affected class or method. Identify any conflicting enhancements that may be causing the ambiguity.
  Refactor Enhancements: If possible, refactor the enhancements to eliminate conflicts. This may involve consolidating enhancements or modifying their logic to ensure they do not interfere with each other.
  Use Enhancement Spots: Ensure that enhancements are applied at the correct enhancement spots. If necessary, create new enhancement spots to avoid conflicts.
  Check Inheritance: Review the inheritance hierarchy of the class in question. Ensure that there are no conflicting methods or properties being inherited from parent classes.
  Consult Documentation: Refer to SAP documentation or notes related to enhancement frameworks and inheritance to understand best practices and guidelines.

  Enhancement Framework: Familiarize yourself with the SAP enhancement framework, which allows developers to add custom functionality to standard SAP applications without modifying the original code.
  ABAP Development Tools: Use tools like the ABAP Workbench (SE80) or Eclipse-based ABAP Development Tools to analyze and manage enhancements.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide guidance on resolving enhancement conflicts.
  Testing: After making changes, thoroughly test the affected functionality to ensure that the ambiguity has been resolved and that the system behaves as expected.
