Hi

IF U want hide that parameter do like this

LOOP AT SCREEN.

IF screen-name = 'po_name'.

screen-active = 0.

MODIFY SCREEN.

EXIT.

ENDIF.

ENDLOOP.

If u want to hide the selection screen text also then debug the code capture the screen names corrosponding to that parameter and give all the screen names in the if condition.

If u r checking for multiple screen names then remove EXIT statement.

Vinod.

Hello,

LOOP AT SCREEN.

All fields of the current screen are stored in the system table SCREEN with their attributes. The LOOP AT SCREEN statement places this information in the header line of the system table. If you want to change the attributes, you must put back the changed header line with MODIFY SCREEN. However, you can only do this in the PBO module of a screen.

If you use this statement for step loop processing, the information (and any changes) apply only to the current steploop line. Outside step loop processing, the information for a step loop field applies to the complete column.

You can also modify fields in the loop processing of a table control using this loop statement. Unlike a step loop, modifications before the loop have no effect, since the system gets the initial values for the columns from the column table of the table view.

Step loop fields should never be changed after the corresponding step loop processing has been performed.

You can use the CONTINUE statement to leave the current loop pass prematurely and continue with the next loop pass.

eg :

loop at screen.

if screen-name = p_name

if p_box = 'X'.

screen-input = 1.

else.

-

---

endif.

endloop.
