RSDD_ZA124 - Details

• The SAP error message RSDD_ZA124 indicates an issue related to the master index server or the backup queue in the context of SAP BW (Business Warehouse) or SAP HANA. This error typically arises when the system is unable to access the necessary master index server or when there is a problem with the backup queue that is supposed to handle requests when the master index server is down.
  
  Cause:
  
  Inactive Master Index Server: The master index server, which is responsible for managing the metadata and data access, may not be running or is not reachable.
  Backup Queue Issues: If the master index server is down, the system should redirect requests to a backup queue. If this backup queue is also inactive or misconfigured, it can lead to this error.
  Network Issues: There may be network connectivity issues preventing access to the master index server.
  
  Configuration Issues: Incorrect configuration settings in the BW or HANA system
