Capture last line item

Question

I have a requirement where in i have to display a pop up with all the line items given by user in ME21N . The pop up has to display when user presses CHECK .
I written the code in the exit EXIT_SAPMM06E_017 . its working fine for single line item.
In case of multiple line items the popup appears for every line item instead of showing all the line items in a single pop up since in the user exit there is no provision of capturing the LAST LINE ITEM . The field EKKO-LPONR which captures the last line item , is populated only after the exit is triggered which captures the value of EKPO-EBELP( line-item). I manage to capture the line items in internal table but unable to capture last line item and then display the internal table in pop up .
If the user gives two line items say 10 , 20 .
Line item 10 is populated to field EKPO-EBELP . After the control comes out of the exit the value of EBELP is assigned to LPONR . At next control LPONR = 10 and EBELP = 20.
Thanks .

Hi Priya,
To show popup for the last line item, try with this logic:
You have an internal table with all line items, take an internal table with same structure. Take the number of lines and read the line iten into work area and append this work area into another table. after that read this second internal table with EBELN and EBELP, if it is matching then show the popup for all line items from first internal table.
Put this code:
<b>dsescribe int_first into ws_lines.
if ws_lines gt 0.
read table int_first into wa_first index ws_lines.
if sy-subrc eq 0.
  append wa_first to int_second.
endif.
endif.
if not int_second is initial.
read int_second into wa_first with key EBELN = 'structure ebeln value'
                                                        EBELP = 'structure ebelp value'
  if sy-subrc eq 0.
   " put POPUP code
  endif.
endif.</b>
Hope it will solve ur problem.
