• What is the cause and solution for SAP error message IUUC_RT012 - Sender system type not supported ?

  The SAP error message IUUC_RT012, which states "Sender system type not supported," typically occurs in the context of SAP Landscape Transformation (SLT) or SAP Data Services when there is an issue with the configuration of the source system or the type of data source being used.
  Cause:
  
  Unsupported Source System: The error may arise if the source system is not recognized or supported by the SLT configuration. This can happen if the source system is not an SAP system or if it is an unsupported version of an SAP system.
  Incorrect Configuration: There may be a misconfiguration in the SLT setup, such as incorrect settings in the configuration of the replication server or the source system.
  Missing or Incorrect RFC Connection: The Remote Function Call (RFC) connection to the source system may not be set up correctly, or the connection may not be active.
  Version Compatibility: The version of the SLT or the source system may not be compatible with each other.
  
  Solution:
  
  Check Source System Compatibility: Ensure that the source system is a supported SAP system and that it is running a compatible version. Refer to the SAP documentation for a list of supported systems.
  Review SLT Configuration: Go through the SLT configuration settings to ensure that everything is set up correctly. This includes checking the configuration of the replication server and ensuring that the source system is correctly defined.
  Verify RFC Connection: Check the RFC connection to the source system. Ensure that it is correctly configured and that the connection is active. You can test the RFC connection using transaction SM59 in the SAP GUI.
  Check for Updates: Ensure that both the SLT and the source system are updated to the latest patches and versions, as updates may resolve compatibility issues.
  Consult SAP Notes: Look for relevant SAP Notes that may address this specific error. SAP Notes often provide fixes or workarounds for known issues.
