• What is the cause and solution for SAP error message VW347 - Function module READ_TABLE_BUFFERED: Parameter 'I_BUFFER_TYPE' incorrect ?

  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 being passed to the function module.
  
  
  Custom Code Issues: If this function module is being called from custom ABAP code, there may be an issue in the way the parameters are being set or passed.
  
  
  Solution:
  To resolve the VW347 error, you can take the following steps:
  
  
  Check Buffer Type: Ensure that the value being passed to the I_BUFFER_TYPE parameter is correct. It should be one of the valid values expected by the function module.
  
  
  Verify Table Buffering: Check if the table you are trying to read is indeed buffered. You can do this by going to the table definition in the Data Dictionary (SE11) and checking the buffering settings.
  
  
  Review Custom Code: If the function module is being called from custom ABAP code, review the code to ensure that all parameters are being set correctly and that the correct data types are being used.
  
  
  Debugging: If you have access to the ABAP debugger, you can set a breakpoint in the code where the function module is called to inspect the values of the parameters being passed.
  
  
  Consult Documentation: Refer to the SAP documentation for the READ_TABLE_BUFFERED function module to understand the expected parameters and their valid values.
