If these buttons are located on application toolbar of the screen then simple [SET PF-STATUS EXLCUDING|http://help.sap.com/abapdocu_70/en/ABAPSET_PF-STATUS_SHORTREF.htm] in PBO of screen will trun your button on or off.

Hi,

When you will go to screen 200 you need to set the pf-status accordingly.

Means in the PBO of the screen 200 you need to give a if condition and accordingly you need to set the PF Status,

In the module of PBO write the code like below -

IF w_index = 1.
  SET PF-STATUS  'STATUS_NAME' EXCLUDING 'BACK' IMMEDIATELY..
ELSEIF  w_index = total_index.
  SET PF-STATUS  'STATUS_NAME' EXCLUDING 'NEXT' IMMEDIATELY.
ELSE.
  SET PF-STATUS  'STATUS_NAME'  IMMEDIATELY.
ENDIF.

Here w_index variable will hold the current index value .

total_index variable will contain the total no entries of the grid, that you can get from the internal by the -


DATA : w_index TYPE i,
             total_index TYPE i.
DESCRIBE TABLE itab LINES total_index.
