Please help me to modify the following code !

SELECT VTEXT FROM TVKGGT

INTO CORRESPONDING FIELDS OF TABLE t_tvkggt

WHERE KDKGR = itab-kdkg1.

read table t_tvkggt with key kdkgr = t_tvkggt-kdkgr binary search.

itab-vtext2 = t_tvkggt-vtext.

I am getting corresponding values of vtext where itab has

values of kdkgr and also doesnt have any values of kakgr.

how to remove those values of vtext which doesnt have any value for kdkgr.
