i also use the FM in this order

1)INITIALIZATION -> REUSE_ALV_VARIANT_DEFAULT_GET

2)AT SELECTION-SCREEN ON VALUE-REQUEST FOR -

>REUSE_ALV_VARIANT_F4

3)AT SELECTION-SCREEN---->REUSE_ALV_VARIANT_DEFAULT_GET

4)start-of-selection.

Hello Anilkumar

Have a look at the following SAP documentation:

<a href="http://help.sap.com/saphelp_47x200/helpdata/en/0a/b5533cd30911d2b467006094192fe3/content.htm">ALV Grid - method SET_TABLE_FOR_FIRST_DISPLAY</a>

and search for <b>I_DEFAULT</b>. There you will find the following remarks:

This parameter determines if the user is allowed to define default layouts:

    * 'X':       Default layouts allowed (default setting)
    * SPACE: Default layouts not allowed

If default layouts are allowed and if such a layout exists and no other layout is specified
in IS_VARIANT , the default layout is automatically loaded when this method is called.

Please note that you will find the same parameter in function module REUSE_ALV_GRID_DISPLAY (or preferrably REUSE_ALV_GRID_DISPLAY_LVC).

Regards

Uwe

thanks floks, i had spotted the problem with my layout selection, "iam sending a SORTINFO internal table to ALV FM that is the reason it is not taking the layout i selected from the selection screen." (if there is any other reasons please let me know).

thanks & regards
