Smart SAP Assistant

• What is the cause and solution for SAP error message R8151 - Invalid transfer method '&1&; '2' only permitted for segmented DataSource ?

  The SAP error message R8151, which states "Invalid transfer method '&1&; '2' only permitted for segmented DataSource," typically occurs in the context of data extraction from SAP systems, particularly when working with DataSources in SAP BW (Business Warehouse) or SAP BI (Business Intelligence).
  Cause:
  This error is related to the transfer method specified for a DataSource. The transfer method '2' refers to a specific way of transferring data, which is only applicable to segmented DataSources. If you are trying to use this transfer method with a non-segmented DataSource, you will encounter this error.
  Solutions:
  
  
  Check DataSource Configuration:
  
  Verify the configuration of the DataSource you are using. Ensure that it is indeed a segmented DataSource if you intend to use transfer method '2'.
  If the DataSource is not segmented, you will need to change the transfer method to one that is compatible with non-segmented DataSources (e.g., transfer method '1').
  
  
  
  Modify Transfer Method:
  
  If you have control over the DataSource settings, you can change the transfer method in the DataSource settings in the SAP BW system. This can usually be done in the DataSource maintenance transaction (e.g., RSA1).
  
  
  
  Consult Documentation:
  
  Review the SAP documentation for the specific DataSource you are working with to understand its characteristics and the appropriate transfer methods.
  
  
  
  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 DataSource handling.
  
  
  
  Contact SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is a production issue.

  Transfer Methods: In SAP BW, transfer methods define how data is transferred from the source system to the BW system. Common methods include:
  
  Method '1': Directly from the source system.
  Method '2': For segmented DataSources, typically used for delta loads.
  
  
  
  Segmented DataSources: These are DataSources that allow for more complex data structures and are often used for specific types of data extraction, such as those involving hierarchical data.
  
  
  Transaction Codes:
  
  RSA1: Data Warehousing Workbench, where you can manage DataSources.
  RSC1: Create DataSource.
  RSC2: Change DataSource.
  RSC3: Display DataSource.
  
  
  
  By following these steps and understanding the context of the error, you should be able to resolve the issue effectively.
