• What is the cause and solution for SAP error message RSM1653 - Source system &1 is a dummy of source system &2 - Only full load allowed ?

  The SAP error message RSM1653 indicates that there is an issue with the data transfer between source systems in a data extraction process, particularly in the context of SAP BW (Business Warehouse) or SAP Data Warehousing. This error typically arises when you are trying to perform a delta load from a source system that is defined as a "dummy" system, which means it is not configured to support delta loads.
  Cause:
  
  Dummy Source System: The source system you are trying to extract data from is marked as a dummy system. Dummy systems are typically used for certain types of data extraction but do not support delta loads.
  Configuration Issues: There may be a misconfiguration in the source system settings or in the data source settings in SAP BW.
  Incorrect Load Type: Attempting to perform a delta load when the source system is only set up for full loads.
  
  Solution:
  
  
  Check Source System Configuration:
  
  Go to the SAP BW system and check the configuration of the source system in transaction RSA1 (Data Warehousing Workbench).
  Ensure that the source system is correctly configured to allow delta loads if that is your intention.
  
  
  
  Use Full Load:
  
  If the source system is indeed a dummy system, you will need to perform a full load instead of a delta load. This can be done by changing the load type in your data transfer process (DTP) settings.
  
  
  
  Adjust Data Source Settings:
  
  Review the data source settings in the source system. Ensure that the data source is set up correctly to allow for the type of load you are attempting (full or delta).
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to your specific version of SAP BW for any additional configuration steps or considerations.
  
  
  
  Check for Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as there may be fixes or enhancements related to data extraction processes.
  
  
  
  Related Information:
  
  Dummy Source Systems: These are typically used for specific scenarios where only full loads are required, such as when the data is not changing frequently or when the data is being loaded from a non-SAP source.
  Delta Load: This is a process that only extracts data that has changed since the last load, which is more efficient than full loads but requires proper configuration of the source system.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to this error message.
  
  By following these steps, you should be able to resolve the RSM1653 error and successfully perform the data load as intended.
