  The SAP error message /IWBEP/GWS004 Exception occurred while executing EPM '&1' typically indicates that there was an exception or error while executing an Enterprise Performance Management (EPM) operation in the SAP Gateway framework. This error can arise from various underlying issues, including configuration problems, data inconsistencies, or issues with the service itself.
  Possible Causes:
  
  Service Configuration Issues: The OData service may not be properly configured or activated in the SAP Gateway.
  Authorization Issues: The user executing the operation may not have the necessary authorizations to access the EPM or the underlying data.
  Data Issues: There may be inconsistencies or errors in the data being processed by the EPM.
  Backend System Errors: The backend system (like SAP S/4HANA or SAP BW) may have encountered an error while processing the request.
  Network Issues: There could be network-related issues affecting the communication between the frontend and backend systems.
