Error Message when delivery qty more then po qty in MV50AFZ1

Question

Hi
Sap Gurus,
I gt a requirement  that while creating deliveries in vl02n
if delivery quantity greater then po qty it should through error
but i have alredy done coding in mv50afz1 user exit its working fine. My problem is if delivery no is differnt for the po no.
it is not giving error because delivery quantity is less for differnt deliveries .
this is the code i have written,
data : v_menge type ekpo-menge,
Getting Quantity from ekpo Table
select single menge
              into v_menge from ekpo
              where ebeln = lips-vgbel
              and ebelp = lips-vgpos.
if sy-subrc = 0.
Cheking the Condition for Delivery Type
   if likp-lfart = 'ZGND' or likp-lfart = 'ZGNL' or likp-lfart = 'ZGNS'.
Cheking Condition if Delivery Quntity More than Po Quantity
    if v_menge < lips-lfimg.
     message e002(zt) with 'Delivery Qty Cannot be Greater than PO Qty'.
    endif.
  endif.
endif.
this is checking for single delivery quantiry greater then po qty
but if multiple deliveries it is not working.
Please suggest me to write logic and coding chages.
