Hi Mateen,
You can use two ways for Search help,
First method.
create one search help in se11 and call that search help name in se51 by double clicking the input field.
but you are telling as a text field first method wont work better try it, because of non primary key fields,
Second method.
In SE 51 after PROCESS AFTER INPUT.
Declare,
PROCESS ON VALUE-REQUEST.
field text-field module help_text.
Double click on help_text before module.
it will open the abap editor,
In that delcare the two Internal tables,
one with table key fields along with the search help fields,
another with only search help fields,
use query to fill the table first internal table with key fields,
then append the search fields to another Internal table from the first Internal table,
after that call the FM . F4_IF_INT_TABLE_VALUE_REQUEST.
pass the internal table name and field name.
Regards,
Venkat.
