VA01 Enhancement Not Working Properly

Hi,

I am doing one enhancement in VA01 inside include MV45AFZZ inside form USEREXIT_SAVE_DOCUMENT_PREPARE.

I am adding a SO line item wise Quantity check against referenced Quotation's Quantity with +ve Tolerance.

Sum of SO quantities item wise shouldn't exceed referenced Quotation's Qty + Over delivery Tolerance in that.

One Peculiar thing is happening when I am calculating the percentage for the above logic in below code is not giving correct values.

ENHANCEMENT 1  ZSD_SOCON_QTY_CHECK.    "ACTIVE VERSION

IF VBAK-VGBEL IS NOT INITIAL.

  DATA: LWA_XVBFA  LIKE XVBFA,
        LV_ZMENG   TYPE DZMENG,
        LV_UEBTO   TYPE UEBTO,
        LV_TOL_QTY TYPE RFMNG,
        LV_SUM_QTY TYPE RFMNG.

  LOOP AT XVBFA WHERE POSNV IS NOT INITIAL.

    SELECT SINGLE ZMENG UEBTO FROM VBAP
           INTO (LV_ZMENG,LV_UEBTO)
           WHERE VBELN = XVBFA-VBELV
           AND POSNR = XVBFA-POSNV.

    LV_TOL_QTY = LV_ZMENG + ( LV_ZMENG * ( LV_UEBTO / 100 ) ).

    LOOP AT XVBFA INTO LWA_XVBFA
         WHERE POSNV IS NOT INITIAL
         AND POSNN EQ XVBFA-POSNN.
      LV_SUM_QTY = LV_SUM_QTY + LWA_XVBFA-RFMNG.
    ENDLOOP.

    IF LV_SUM_QTY > LV_TOL_QTY.
      MESSAGE 'SO Qty Exceeds Contract Qty + Tolerance' TYPE 'E'.
    ENDIF.
  ENDLOOP.

ENDIF.

ENDENHANCEMENT.

Taking a example:

OutPut

LV_ZMENG 150000.000

LV_UEBTO 10.0

LV_TOL_QTY 300000.000

I checked with a Sample SE38 program.Calculation is happening correctly in that.but i dont know why it is behaving like this.

I have checked all the possibilities to resolve that,data type format of destination variable, watch points whether it is changing for other reason etc.

thanks in advance for early reply.
