• What is the cause and solution for SAP error message R8424 - The extraction view &1 of DataSource &2 has the wrong type ?

  The SAP error message R8424 indicates that there is a mismatch in the data types between the extraction view and the DataSource in SAP BW (Business Warehouse). This typically occurs when the structure of the extraction view does not match the expected structure defined in the DataSource.
  Cause:
  
  Data Type Mismatch: The fields in the extraction view may have different data types or lengths compared to those defined in the DataSource.
