As from SAP help -

... MODIF ID modid

Effect

The addition MODIF ID assigns all the screen elements of the parameter to the modification group modid, which is assigned to the column group1 of the system table screen. This enables them to be modified before the selection screen is displayed, using the statement MODIFY SCREEN. The name of the modification group modid must be directly specified and can have a maximum length of three characters.

Note

The modification groups that are assigned to columns group2 and group3 of the system table screen are set when the system generates a selection screen and are described in the screen elements of a selection screen.

Example:

The elements of block b2 are assigned to the modification group bl2. A checkbox show_all allows the user to select whether or not these elements are displayed. The display is changed immediately, as selecting the checkbox triggers the event AT SELECTION-SCREEN. The function code is not required. Instead, the content of show_all is evaluated during PBO.

PARAMETERS show_all AS CHECKBOX USER-COMMAND flag.

SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME.

PARAMETERS: p1(10) TYPE c,

p2(10) TYPE c,

p3(10) TYPE c.

SELECTION-SCREEN END OF BLOCK b1.

SELECTION-SCREEN BEGIN OF BLOCK b2 WITH FRAME.

PARAMETERS: p4(10) TYPE c MODIF ID bl2,

p5(10) TYPE c MODIF ID bl2,

p6(10) TYPE c MODIF ID bl2.

SELECTION-SCREEN END OF BLOCK b2.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF show_all <> 'X' AND

screen-group1 = 'BL2'.

screen-active = '0'.

ENDIF.

MODIFY SCREEN.

ENDLOOP.

HI Akshithta

This Modif id is used to make the variables into one group

You can change these two variables in a single step

as

Loop at Screen

IF screen-group1 = 'SL2'.

SCREEN-ACTIVE = 0.

ENDIF.

endloop.

WITH THIS CODE ALL THE VARIABLES BELONGS TO THIS MODIF ID S1 WILL BE EFFECTED

If it helps reward with points

Hi Akshita,

MODIF ID is used to group a set of fields under the name associated with it.

Hope this resolves your query.

Reward all the helpful answers.

By specifying the modif id, we are logically grouping a set of parameters of the selection screen.

If you want tose ta screen property for a set of fields, dynamically, you can simple use the modif id value as follows.

• To make a group of fields input disabled at run time

at selection-screen output.
loop at screen.
if screen-group1 = 'SI2'.
screen-input = 0.
modify screen.
endif.
endloop.

Hi....

In Selection screen MODIF ID represents the Group Name..

Grouping Certain Screen Elements by unique Name..

Try this Example,,

SELECTION-SCREEN : BEGIN OF BLOCK blk1 WITH FRAME TITLE text-001.

PARAMETERS: number(10) TYPE c MODIF ID gr1.

SELECTION-SCREEN : END OF BLOCK blk1.

SELECTION-SCREEN : BEGIN OF BLOCK blk2 WITH FRAME TITLE text-001.

SELECTION-SCREEN BEGIN OF LINE.

PARAMETERS: name(10) MODIF ID gr2.

SELECTION-SCREEN END OF LINE.

SELECTION-SCREEN : END OF BLOCK blk2.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN .

IF screen-group1 EQ 'GR2'.

screen-active = 0.

MODIFY SCREEN.

ENDIF.

ENDLOOP.
