Hi,

Modif-id is used for grouping of parameters.With this,you can make modifications to a group of parameters like make a group editable or display mode only.

Check this link.It has the usage with a sample code:

            test4(10) TYPE c MODIF ID sc2.

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF screen-group1 = 'SC1'.

This addition assigns screen objects ( Comment, Underscore line, Parameter, ...) to a modification group and hence allows dynamic modification of the selction screen display.

The modification group name modid must be specified directly and must be no longer than 3 characters. The addition MODIF ID assigns modid to the column SCREEN-GROUP1 of the predefined internal table SCREEN. Parameters assigned to a modification group can be changed together using the LOOP AT SCREEN and MODIFY SCREEN statements at the event AT SELECTION SCREEN OUTPUT.

AT SELECTION SCREEN OUTPUT.

loop at screen.

if SCREEN-GROUP1 = 'MOD'.

screen-input = '0'.

MODIFY SCREEN

endloop.

here you can change the attribute of parameter or select-option dynamically.

Hi vijay,

At selection-screen is the event in ABAP evironemt

.When user midifies some data in the selection scrren , and wants to reflect the change dynamically in the screen after hitting Enter or Clicking ,

At selction-Screen output is fired

ex.

tables:vbak

selection-screen: z_vbak for vbak-vbeln modif id xyz.

at selection-screen output.

if screen-group1 = 'xyz'..

ur logic.

endif

..here in this case , for selction screen ,there is a dictionary table called 'SCREEN'

is all the time updated .

Modiff ID is used to specifically refere to that select option .

Also there are groups called Gruop1 , Gruop2 ,etc. which are used tocategorised the select-options as per purpose.

More help can be obtained from ABAP Documenataion.(F1 help on keyword)

I guess this answers ur doubt.

Regards.
