User exit doubt

Question

Hi experts,
Iam trying to write userexit using MV45AFZB.
If AUART eq ZR01 & ZR02 and price limit(NETWR) is greater than 500,I want to raise the messgae.
data: v_total like vbap-netwr.
check xvbak-auart = 'ZR01' or
      xvbak-auart = 'ZR02'.
loop at xvbap where abgru = 'ZC'.
     v_total = v_total + xvbap-netwr.
endloop.
if v_total gt 500.
      message e000(zmsg) with
         'FOC sales order limit exceeded!'.
endif.
I have written this code in FORM USEREXIT_SAVE_DOCUMENT_PREPARE(MV45AFZB) subroutine.
It is not triggering when Amount is more that 500.What might be the reason? Where i need to write this program?
MV45AFZB or MV45AFZZ?And also let me know the subroutine.
When i press enter, i want display message.
Reward guaranteed
thanks

Hi Kaki,
You can code something like this and please debug it (if needed).
data: v_total like vbap-netwr,
      v_gtotal type i.
check xvbak-auart = 'ZR01' or
      xvbak-auart = 'ZR02'.
loop at xvbap where abgru = 'ZC'.
     v_total = v_total + xvbap-netwr.
endloop.
move v_total to v_gtotal.
if v_gtotal > '500'.
  message e000(zmsg) with
          FOC sales order limit exceeded!'.
endif.
Hope this will help.
