XVBAP has the new line item but does not update Sales Order

Question

Hi
I need to update the sales order with a new line item when the line item has a base unit of measure as the sales unit. I need to then convert the base unit to sales unit with a whole figure and the rest can be in the base unit.
I am able to see the update in the xvbap but the line item doesn't get updated.
I am puting this code in a perform within
MV45AFZB  within   Form  USEREXIT_CHECK_VBAP
But I guess I am doing something wrong can someone please take a look at it and tell me what is wrong with the coding.
*&  Include       ZSD_CREATE_NEW_LINE_ITEM              *
*&      Form  create_new_line_item
      text
-->  p1        text
<--  p2        text
FORM CREATE_NEW_LINE_ITEM .
  CONSTANTS: C_MEINH LIKE MARM-MEINH VALUE 'CSE'.
Variables Used
  DATA: WS_WMENG LIKE VBEP-WMENG.
  DATA: INPUT  LIKE VBAP-KWMENG,
        WS_EA  LIKE VBAP-KWMENG,
        WS_CSE LIKE VBAP-KWMENG.
  DATA: WS_MVKE_VRKME LIKE MVKE-VRKME.
Internal Tables and Structures
  DATA: WS_XVBAP LIKE XVBAP.
DATA:
it_vbap  LIKE vbap OCCURS 0 WITH HEADER LINE,
it_vbep  LIKE vbep OCCURS 0 WITH HEADER LINE,
it_xvbap LIKE vbapvb OCCURS 0 WITH HEADER LINE.
  DATA: BEGIN OF WS_MARM,
          MEINH LIKE MARM-MEINH,
          UMREZ LIKE MARM-UMREZ,
          UMREN LIKE MARM-UMREN,
        END OF WS_MARM.
  CLEAR WS_MVKE_VRKME.
  SELECT SINGLE VRKME INTO WS_MVKE_VRKME
    FROM MVKE
    WHERE MATNR EQ XVBAP-MATNR
    AND   VKORG EQ XVBAK-VKORG
    AND   VTWEG EQ XVBAK-VTWEG.
  IF VBAP-VRKME <> WS_MVKE_VRKME.
   LOOP AT XVBAP.
      SELECT SINGLE MEINH UMREZ UMREN
        FROM MARM
        INTO WS_MARM
        WHERE MATNR = VBAP-MATNR
        AND   MEINH = WS_MVKE_VRKME.
      IF XVBAP-MEINS <> WS_MVKE_VRKME.
        IF NOT XVBAP-KWMENG = 0.
          WS_WMENG = XVBAP-KWMENG / WS_MARM-UMREZ.
          IF WS_WMENG > 1.
This means that the line item needs to be split into CSE & EA
              INPUT  = XVBAP-KWMENG.
              WS_EA  = INPUT / WS_MARM-UMREZ.
              WS_CSE = WS_EA.
              WS_EA  = WS_CSE * WS_MARM-UMREZ.
              WS_EA  = INPUT - WS_EA.
Now we have the qty. split into EA & CSE. Now to
assign it to xvbap
              XVBAP-KWMENG = WS_EA.
              XVBAP-VRKME  = WS_MVKE_VRKME.
          READ TABLE XVBAP WITH KEY POSNR = XVBAP-POSNR.
            MODIFY XVBAP INDEX SY-TABIX.
              WS_XVBAP = XVBAP.
              WS_XVBAP-KWMENG = WS_CSE.
            MOVE-CORRESPONDING WS_XVBAP TO XVBAP.
            INSERT XVBAP INDEX SY-TABIX.
          ENDIF.
        ENDIF.
      ENDIF.

Hi Clark,
Pls check the Include MV45AFZZ instead of the one which you are using . Here in this include MV45AFZZ you can have access to the Header and Line items data .
Here in this include
      FORM USEREXIT_SAVE_DOCUMENT                                   *
      This userexit can be used to save data in additional tables   *
      when a document is saved.                                     *
      If field T180-TRTYP contents 'H', the document will be        *
      created, else it will be changed.                             *
      This form is called at from form BELEG_SICHERN, before COMMIT *
form userexit_save_document.
Endform.
Either you can write the code you want to update the XVABP table here or you can use the form .
      FORM USEREXIT_MOVE_FIELD_TO_VBAP                              *
      This userexit can be used to move some fields into the sales  *
      dokument item workaerea VBAP                                  *
      SVBAP-TABIX = 0:  Create item                                 *
      SVBAP-TABIX > 0:  Change item                                 *
      This form is called at the end of form VBAP_FUELLEN.          *
form userexit_move_field_to_vbap.
endform.
This are the 2 performs in this include where you can do you code and it will defnitely solve your problem.
Good Luck to you . Let me know if your problem get solved.
Thanks & Regards,
Naidu.
