• What is the cause and solution for SAP error message RSM810 - Source system & does not exist ?

  The SAP error message RSM810 typically indicates that the source system you are trying to access or work with does not exist in the system landscape. This error can occur in various contexts, such as during data extraction, data loading, or when trying to access data from a source system in SAP BW (Business Warehouse) or other SAP modules.
  Cause:
  
  Incorrect Source System Configuration: The source system may not be properly configured in the SAP system. This could be due to missing entries in the relevant tables or incorrect settings.
  Source System Not Defined: The source system you are trying to access has not been defined in the SAP BW system.
  Transport Issues: If the source system was recently transported from another environment (like Development to Production), it may not have been set up correctly.
  Authorization Issues: The user may not have the necessary authorizations to access the source system.
  Network Issues: There could be connectivity issues between the SAP system and the source system.
  
  Solution:
  
  
  Check Source System Configuration:
  
  Go to transaction RSA1 (Data Warehousing Workbench).
  Navigate to the "Source Systems" section and verify if the source system is listed.
  If it is not listed, you may need to create it using the appropriate configuration steps.
  
  
  
  Define the Source System:
  
  If the source system is not defined, you can create it by using transaction RSA1 and selecting the option to create a new source system.
  Ensure that you provide the correct technical details (like RFC destination, system type, etc.).
  
  
  
  Check Transport Requests:
  
  If the source system was recently transported, check the transport logs to ensure that all necessary objects were transported correctly.
  If there are missing objects, you may need to re-transport them.
  
  
  
  Verify Authorizations:
  
  Ensure that the user has the necessary authorizations to access the source system. This can be checked in transaction SU01 (User Maintenance) or by consulting with your security team.
  
  
  
  Network Connectivity:
  
  Check if there are any network issues preventing access to the source system. This may involve checking firewall settings, network configurations, or contacting your IT support team.
  
  
  
  Check for System Updates:
  
  Sometimes, system updates or patches may affect the configuration. Ensure that your SAP system is up to date and that any relevant notes from SAP have been applied.
