[Former Member]

Hi,

I have a requirement to display the out put in ALV Grid and in the display there should be a Change,Refresh Push buttons.

when click on change button it will call some transaction and we will make the chages.

when we click on Refresh button it has to display the screen with the changes what we made earlier if any.

so i coded everthing is working fine except iam getting new screen with all the modifications when i click on Refresh button and when i click back it will go to the previous screen.

So my requirement is i want only one screen to be displayed when i click on Refresh button.

Hope iam clear in the question so can any one help me out to resolve this issue thanks in advance.

Hi,

This is the code for the Refresh button

WHEN 'REFRESH'.

CLEAR ITAB_FINAL.

REFRESH ITAB_FINAL.

PERFORM GET_DATA.

PERFORM GRID_DISP.

Hi,

I think you are deleting the internal table, re creating it and then recreating the ALV grid, instead try getting the data and refresh the ALV display using the method REFRESH_TABLE_DISPLAY.
