MB_DOCUMENT_BADI - MB_DOCUMENT_BEFORE_UPDATE : how to check serial number

Question

Hello,
we would like to check serial numbers just before saving our document.
How could we read the serial numbers from memory ?
The GET_SERNOS_OF_DOCUMENT does not return data from memory !
Do you know a function to catch those datas ?
Best regards

Hello Kesav,
If we use the customer exit EXIT_SAPLIPW1_008, we have a select in SER05 and OJBK for each serial numbers.
                                 => 200 serial = 200 select.
The use of the BADI would be a better solution  => only one SELECT .... into t_tab and then one READ for each SN.
The use of GET_SERNOS_OF_DOCUMENT  :
data : ls_rser  TYPE rserob,
          lt_sernos TYPE TABLE OF rserob.
    move: x_mkpf-mblnr to ls_rser-mblnr,
               x_mkpf-mjahr to ls_rser-mjahr,
              'SER03'            to ls_rser-taser.
  CALL FUNCTION 'GET_SERNOS_OF_DOCUMENT'
    EXPORTING
      KEY_DATA            = ls_rser
    TABLES
      sernos                   = lt_sernos
    EXCEPTIONS
      KEY_PARAMETER_ERROR = 1
      NO_SUPPORTED_ACCESS = 2
      NO_DATA_FOUND              = 3.
  Result = NO_DATA_FOUND (True, because we have no SN in SER03 for the specified document => not saved).
This function seems not to be the good way to catch our SN from memory !
