• What is the cause and solution for SAP error message RSAR248 - Error when determining the technical name of the InfoSource ?

  The SAP error message RSAR248 typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the InfoSource configuration or when the system is unable to determine the technical name of the InfoSource during data extraction or loading processes.
  Cause:
  
  Missing or Incorrect InfoSource: The InfoSource you are trying to use may not exist, or its technical name may be incorrectly specified in the data flow or transformation.
  Transport Issues: If the InfoSource was recently transported from another system, it may not have been activated properly in the target system.
  Authorization Issues: The user executing the process may not have the necessary authorizations to access the InfoSource.
  DataSource Configuration: There may be issues with the DataSource that feeds into the InfoSource, such as incorrect settings or missing fields.
  Technical Name Changes: If the technical name of the InfoSource was changed after it was created, the system may not be able to find it.
  
  Solution:
  
  Check InfoSource Existence: Verify that the InfoSource exists in the system. You can do this by navigating to the InfoSource maintenance transaction (RSA1) and checking the InfoSources under the relevant InfoArea.
  Validate Technical Name: Ensure that the technical name of the InfoSource is correctly specified in the data flow or transformation. You can check this in the Data Flow or Transformation settings.
  Activate InfoSource: If the InfoSource was recently transported, ensure that it is activated. You can do this in RSA1 by selecting the InfoSource and choosing the activation option.
  Check Authorizations: Ensure that the user has the necessary authorizations to access the InfoSource. You may need to consult with your security team to verify this.
  Review DataSource Settings: Check the configuration of the DataSource that feeds into the InfoSource. Ensure that all required fields are correctly mapped and that the DataSource is functioning properly.
  Recreate InfoSource: If the InfoSource is corrupted or not functioning as expected, consider recreating it. This should be done with caution and ideally in a development environment first.
