• What is the cause and solution for SAP error message R8164 - Only generic interfaces are allowed for extraction method &1 ?

  The SAP error message R8164, which states "Only generic interfaces are allowed for extraction method &1," typically occurs in the context of data extraction processes, particularly when working with SAP BW (Business Warehouse) or SAP HANA. This error indicates that the extraction method you are trying to use is not compatible with the expected interface type.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Non-generic Interface: The extraction method you are trying to use is not defined as a generic interface. In SAP BW, generic data sources are used to extract data from non-SAP sources or from SAP sources that do not have a predefined extractor.
  Incorrect Configuration: The data source or extraction method may not be configured correctly in the SAP system.
  Version Compatibility: There may be compatibility issues between the version of SAP BW and the data source or extraction method being used.
  
  Solution:
  To resolve the R8164 error, you can take the following steps:
  
  
  Check the Extraction Method:
  
  Ensure that the extraction method you are using is indeed a generic interface. You can do this by checking the configuration in the SAP BW system.
  If you are using a custom extraction method, verify that it is implemented correctly as a generic interface.
  
  
  
  Review Data Source Configuration:
  
  Go to the Data Source configuration in the SAP BW system (transaction code RSA1).
  Check the settings for the data source and ensure that it is set up to use a generic interface.
  
  
  
  Use a Generic Data Source:
  
  If the extraction method is not generic, consider creating a new generic data source that can accommodate the data extraction requirements.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific extraction method and data source you are using. There may be specific guidelines or prerequisites that need to be followed.
  
  
  
  Check for Updates:
  
  Ensure that your SAP system is up to date with the latest patches and updates, as there may be fixes related to this issue in newer versions.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after checking the above points, consider reaching out to SAP support for further assistance. They can provide insights based on the specific configuration and version of your SAP system.
  
  
  
  Related Information:

  SAP Notes: Search for SAP Notes related to error R8164 in the SAP Support Portal for any specific fixes or recommendations.
  Documentation: Review the SAP BW documentation for best practices on setting up data sources and extraction methods.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
