Hi Bikas,

You can try this using event AT SELECTION-SCREEN OUTPUT.

Please check this code

PARAMETERS: p_ebeln TYPE ekko-ebeln,
           p_check TYPE c AS CHECKBOX USER-COMMAND us.

AT SELECTION-SCREEN OUTPUT.
  IF p_check IS INITIAL.
    LOOP AT SCREEN.
      IF screen-name = 'P_EBELN'.
        screen-input = 0.
        MODIFY SCREEN.
      ENDIF.

    ENDLOOP.
  ENDIF.

Best regards,

raam

Hi,

The modify screen statement enables you to make modifications on the screen like display/hide...

Syntax

MODIFY SCREEN FROM wa.

Effect

This statement can be used in the statement block after LOOP AT SCREEN only and makes sense only during PBO processing. If FROM is not specified, MODIFY SCREEN modifies the attributes of the current screen element with the values from the predefined screen work area. If a wa work area is specified, its contents are used for the modification.

The wa work area must have the same data type as screen. The name component must contain the name of the current screen element, otherwise the statement is not executed. nweisung nicht ausgeführt. Up to the group1 to group4 and length components, all remaining components of screen and wa must contain either the value 0 or 1. The value 0 deactivates the corresponding field attribute, and 1 activates it.

If MODIFY SCREEN is executed during PBO processing, the modified attributes for the display of the screen affect the current dynpro after PBO processing. The attributes of the screen element of the dynpro are reset to their static attributes at the start of each PBO processing, so that the execution of MODIFY SCREEN during PAI processing does not effect the display of the following screen.

The active component

The active component is used to set the input, output and invisible components at once. At the start of PBO processing, the active component always has the value 1. If active is set to 0 with MODIFY SCREEN, input and output are automatically set to 0 and invisible is set to 1. Other values in input, output and invisible are ignored. Conversely, setting input and output to 0 and invisible to 1 automatically sets active to 0 and a different value in active is ignored.

Modifications in Table Controls and Step Loops

During processing of a table control or a step loop, the changes affect the current line of the table control or the current step loop group. Before the processing of a table control, the change to the attributes of a screen element that is part of a line in the table control does not effect the table control, since the values are transferred from the structure created using CONTROLS. Before a step loop is processed, the change to the attributes of a screen elements that is part of a step loop group affects all groups in the step loop.

Modifications to Tabstrip Controls

If the active component for a tab title of a tabstrip control is set to 0, the whole tabstrip page is hidden.

Example

In the following PBO module, an input field called val is made mandatory and converted to display in the foreground.

MODULE modify_0100 OUTPUT.

LOOP AT SCREEN.

IF screen-name = 'VAL'.

screen-required = '1'.

screen-intensified = '1'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDMODULE.

In your case use screen-active = 1.

Subash.

Hi....

You dont make that button disable from screen painter level....

Better to use both disable and anable logics in program itself, With that MODIFY and LOOP AT SCREEN statements.

Thanks,

Naveen Inuganti.

Hi,

As you have already made the input field input disabled, so in the PBO module write the below code for input Enable.



Case sy-ucomm.
 when 'BUTTON'. " Function code for the button in capital
  Loop at screen.
    if screen-name CS 'FIELDNAME'.  " Field name in Capital 
  Screen-input = 1.
Modify screen.
Endif.
Endloop.
Endcase.

Sujit

Hi,

First set the input field property as a disable (I mean remove the mark from the Attributes --> Program --> Input field ).

Write the following code in PAI

PROCESS AFTER INPUT.

MODULE ip_enable.

Write the following code in report

MODULE ip_enable INPUT.

Case sy-ucomm.

when 'BUTN'.

Loop at screen.

If screen-name = 'INPUT1'.

screen-input = 1. // It enables the input field

MODIFY SCREEN.

ENDIF.

ENDLOOP.

ENDCASE.

ENDMODULE.

I hope this work...

Regards,

Harish
