  The SAP error message FKK_SCALE_OUT043 indicates that a colocation group is assigned to multiple index servers, which is not allowed. This error typically arises in the context of SAP Convergent Charging (SAP CC) or SAP Convergent Invoicing (SAP CI) when dealing with scale-out configurations.
  Cause:
  The error occurs when:

  If you find that a colocation group is incorrectly assigned to multiple index servers, reassign it to the appropriate index server.
  You can do this through the SAP CC or CI configuration interface.
  
  
  
  Consult Documentation:
  
  Refer to the official SAP documentation for guidelines on configuring colocation groups and index servers. This can provide insights into best practices and configuration requirements.
