Display recods when cliking save in screen painter

Question

Hi all,
I am dispalying a table using screen painter.I have 5 records in my internal table.
My need is if i click "save" button in PAI first record should be displayed in the table,
again if i click the "save" button then next record from internal table should be displayed by replacing
first record and so on... until last record it shld be done.
I did it but records are not displayed one by one.
Kindly any one can  provide the required solution.

Hi dinesh,
First we declare a global variable type i.
if sy-ucomm = 'SAVE' and glob_var is initial.
describe table int_table lines glob_var.
......count the total number of records
endif.
case sy-ucomm.
when save.
........if u need a particular order like 1,2,3,4,5
........sort internal table as 5,4,3,2,1....
........read the last record => u will read 1
sort int_tab by field descending
read table int_table index glob_var.  ( n = 5 )
........u have the required data in int_table's work area ..do the needful
........coding to process it
if glob_var > 0.   "if read index is done for index 0 ..shortdump will occur
glob_var = glob_var - 1.
endif.
.........decrement counter so that in next loop we read the nearby record
so everytime u press save...the table index read will be that of the next immediate record
based on the sort order
Hope it helps,Pls check and revert
