I tried for 'search'for results from ITAB, with the following code.
str3 = request->get_form_field( 'REQID' ).
SELECT * FROM STD INTO CORRESPONDING FIELDS OF TABLE itab where REQID LIKE STR2.
But this is not working .Please mail me , as I really struck here.
If you are not getting any value into str3 attribute, try using this:
CALL METHOD request->get_form_field EXPORTING name = 'REQID' RECEIVING value = str3.
Hope this helps you.
