• What is the cause and solution for SAP error message RSAR029 - Source system &1 may not have the same name as the release ?

  The SAP error message RSAR029 indicates that there is a naming conflict between the source system and the release version in the SAP system landscape. This error typically arises in the context of SAP BW (Business Warehouse) when trying to connect to a source system that has a name that does not conform to the expected naming conventions.
  Cause:
  The error occurs when the name of the source system (as defined in the SAP BW system) is the same as the release version of the SAP system. For example, if the source system is named "SAP_700" and the release version is also "700", this will trigger the error. SAP requires that the source system name and the release version be distinct to avoid confusion and ensure proper data extraction and loading processes.

  To resolve the RSAR029 error, you can take the following steps:
  
  
  Change the Source System Name:
  
  Go to the SAP BW system.
  Navigate to the source system configuration (Transaction code: RSA1).
  Locate the source system that is causing the error.
  Change the name of the source system to something that does not conflict with the release version. For example, you could rename "SAP_700" to "SAP_700_SRC".
  
  
  
  Check Naming Conventions:
  
  Ensure that the new name adheres to SAP's naming conventions and does not include any special characters or spaces that might cause issues.
  
  
  
  Update Data Sources:
  
  After renaming the source system, ensure that any data sources or transformations that reference the old source system name are updated accordingly.
  
  
  
  Test the Connection:
