  The SAP error message MSG_CL_ER031 indicates that there is an issue with the configuration of the Services Registry in your SAP system. Specifically, it suggests that there can only be one primary Services Registry configured, and the system has detected that there may be more than one or that the configuration is incorrect.
  Cause:
  
  Multiple Primary Registries: The most common cause of this error is that there are multiple entries in the Services Registry configuration where more than one registry is marked as primary.
  Configuration Error: There may be a misconfiguration in the settings of the Services Registry, leading the system to believe that there are multiple primary registries.
  Data Inconsistency: There could be inconsistencies in the data stored in the system regarding the Services Registry.
  
  Solution:
  
  
  Check Configuration:

  If there are unnecessary or duplicate registries, consider deleting or deactivating them to resolve the conflict.
  
  
  
  Check for Transport Issues:
  
  If the configuration was recently transported from another system, ensure that the transport did not inadvertently create duplicate entries.
