Help need in code

Question

Hi all,
Good morning all
PROCESS BEFORE OUTPUT.
module no_lines.------1
MODULE STATUS_9100.
  loop at itab  with control
          table_control cursor table_control-current_line.
   module get_data.----
2
  endloop.
1)data li_lines type i.
describe table itab lines li_lines.
table_control-lines = table_control-lines + 20.
2)
zabc-matnr = itab-matnr.
zbac-maktx = itab-maktx.
I when i first go into the screen 9100 my
table_control-top_line =1
table_control-current_line = 1.
when i fill the data in the table control which can upto 12 records and hit enter then
table_control-top_line =1
table_control-current_line = 1.
the current_line goes from 1 to 12.
when i drag the the vertical bar then
table_control-top_line =2
table_control-current_line = 2.
the current_line goes from 2 to 13
now my internal table has 12 records ,but since the current_line is initially 2 the data from second record of internal table itab is moved into table control.
now my table control has 11 starting with the second record of internal table and an empty row at the bottom.
I am losing the first record.
I need all the records with an empty rows at the bottom

hi,
You need to call the FM SCROLLING_IN_TABLE for scrolling. You need to call it in the tc_table_user_command of the screen. Capture the ok_code and call the FM accordingly.
    call function 'SCROLLING_IN_TABLE'
         exporting
              entry_act             = tc_table-top_line
              entry_from            = 1
              entry_to              = tc_table-lines
              last_page_full        = 'X'
              loops                 = v_tc_table_lines
              ok_code               = 'P+' "This is for scrolling down
              overlapping           = 'X'
         importing
              entry_new             = l_tc_new_top_line
         exceptions
              NO_ENTRY_OR_PAGE_ACT  = 01
              NO_ENTRY_TO           = 02
              NO_OK_CODE_OR_PAGE_GO = 03
              others                = 0.
You can call this FM in a form with ok_code as parameter to handle all page up(P-), page down(P), first page(P--) and last page(P+)
This will give the new top line and retain the data (ie first record)in the internal table.
Hope this solves the issue.
Regards,
Richa.
