VW347 - Details

• The SAP error message VW347, which states "Function module READ_TABLE_BUFFERED: Parameter 'I_BUFFER_TYPE' incorrect," typically occurs when there is an issue with the parameters being passed to the function module READ_TABLE_BUFFERED. This function module is used to read data from buffered tables in SAP.
  
  Cause:
  The error is usually caused by one of the following reasons:
  
  
  Incorrect Buffer Type: The parameter I_BUFFER_TYPE is expected to have a specific value that indicates the type of buffer being accessed (e.g., 'A' for application buffer, 'C' for client buffer). If an invalid value is passed, the function module will raise this error.
  
  
  Table Not Buffered: The table you are trying to read may not be configured for buffering in the SAP system. If the table is not buffered, the function module will not be able to read it using the buffered read method.
  
  
  Data Type Mismatch: There may be a mismatch in the expected data types for the parameters
