• What is the cause and solution for SAP error message DMC_IU103 - Error while reading system information via RFC connection &1 ?

  The SAP error message DMC_IU103 indicates that there is an issue while reading system information via an RFC (Remote Function Call) connection. This error typically arises in the context of SAP Data Management and Cloud solutions, particularly when there is a problem with the connectivity or configuration of the RFC connection.
  Causes:
  
  RFC Connection Issues: The RFC connection may not be properly configured or may be down. This could be due to network issues, incorrect connection parameters, or the target system being unavailable.
  Authorization Problems: The user credentials used for the RFC connection may not have the necessary authorizations to access the required system information.
  System Configuration: The target system may not be configured correctly to allow RFC calls, or there may be issues with the SAP Gateway.
  Version Compatibility: There may be compatibility issues between the systems involved, especially if they are running different versions of SAP.

  Solutions:
  
  
  Check RFC Connection:
