• What is the cause and solution for SAP error message RSDHA091 - Data target and data source must be different ?

  The SAP error message RSDHA091, which states "Data target and data source must be different," typically occurs in the context of data extraction and loading processes in SAP BW (Business Warehouse) or SAP BW/4HANA. This error indicates that there is a configuration issue where the data target (the destination where data is being loaded) and the data source (the origin of the data) are incorrectly set to the same object.
  Cause:
  
  Misconfiguration: The most common cause of this error is that the data source and data target are configured to be the same object. For example, if you are trying to load data from an InfoObject to the same InfoObject, this will trigger the error.
  Incorrect Data Flow: The data flow might be incorrectly defined in the data transfer process (DTP) or in the InfoPackage.
  Duplicate Objects: Sometimes, there might be confusion due to duplicate objects or similar names in the system.
  
  Solution:
  To resolve the RSDHA091 error, you can follow these steps:
  
  
  Check Data Source and Data Target:
  
  Go to the Data Transfer Process (DTP) or InfoPackage that is causing the error.
  Verify that the data source and data target are indeed different. For example, if your data source is an InfoProvider, ensure that the data target is a different InfoProvider or a different type of object.
  
  
  
  Modify the DTP/InfoPackage:
  
  If you find that the data source and target are the same, modify the DTP or InfoPackage to point to the correct data target.
  Ensure that the data flow is logically correct and that the data is being extracted from one source and loaded into a different target.
  
  
  
  Check for Duplicates:
  
  Ensure that there are no duplicate objects with similar names that might be causing confusion in the configuration.
  
  
  
  Test the Configuration:
  
  After making the necessary changes, test the DTP or InfoPackage to ensure that the error is resolved and that data can be successfully loaded.
  
  
  
  Consult Documentation:
  
  If you are unsure about the configuration, refer to SAP documentation or consult with a BW consultant for best practices in setting up data flows.
