• What is the cause and solution for SAP error message CH139 - Change number '&' is not allowed for classification ?

  The SAP error message CH139, which states "Change number '&' is not allowed for classification," typically occurs when there is an attempt to use a change number that is not valid for a classification object in SAP. This error is often encountered in the context of change management and classification in SAP's Product Lifecycle Management (PLM) or Engineering Change Management (ECM) modules.
  Cause:
  
  Invalid Change Number: The change number you are trying to use may not be valid for the classification you are working with. This can happen if the change number is not assigned to the relevant object or if it is not in the correct status.
  Change Number Status: The change number may be in a status that does not allow it to be used for the classification. For example, it might be in a "not released" status.
  Authorization Issues: The user may not have the necessary authorizations to use the specified change number.
  Configuration Issues: There may be configuration settings in the classification system that restrict the use of certain change numbers.
  
  Solution:
  
  Check Change Number Validity: Verify that the change number you are trying to use is valid and correctly assigned to the object you are working with. You can do this by checking the change number in the change management transaction (e.g., transaction code CC01 for creating change numbers).
  Review Change Number Status: Ensure that the change number is in a status that allows it to be used for classification. If it is not released, you may need to release it or change its status.
  Authorization Check: Ensure that you have the necessary authorizations to use the change number. You may need to consult with your SAP security team to verify your permissions.
  Configuration Review: If the issue persists, review the configuration settings related to classification and change management. This may involve checking the settings in the customizing transactions (e.g., SPRO) to ensure that there are no restrictions on the use of change numbers.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on the specific classification and change management processes relevant to your organization.
