  The SAP error message SEPM_EXCEPTIONS024 indicates that there is an issue with an alternative key field that is expected to exist for a Business Object (BO) node but does not. This error typically arises in the context of SAP's Business Object Processing Framework (BOPF) or when working with SAP Gateway services.
  Cause:
  
  Missing Alternative Key Definition: The alternative key field specified in the error message (&1) is not defined in the metadata for the Business Object node (&2). This could happen if the alternative key was not created or was deleted.
