• What is the cause and solution for SAP error message SMOIWS098 - Host &1 belongs to local system &2. Registration not allowed ?

  The SAP error message SMOIWS098 indicates that there is an issue with the registration of a host in the SAP system landscape. Specifically, the message states that the host you are trying to register belongs to the local system, and therefore, registration is not allowed.
  Cause:
  This error typically occurs in the context of SAP's Landscape Management or when dealing with system registration in the SAP Solution Manager. The main causes include:

  Use transaction SM51 to view the list of active application servers and confirm the host's status.
  
  
  
  Check System Landscape Configuration:
  
  Go to the SAP Solution Manager and check the system landscape configuration. Ensure that the local system is correctly defined and that there are no duplicate entries.
  Use transaction SOLMAN_SETUP to access the configuration settings.
  
  
  
  Review Registration Process:
  
  If you are trying to register a new system, ensure that you are using the correct registration process. Follow the steps outlined in the SAP documentation for registering systems in the Solution Manager.
  
  
  
  Network and DNS Configuration:
