Loop at parameters from selection-screen.

Hi guys,

In my report I have three blocks on selection screen, each block has three parameters and one select-option and I am trying to make dynamic SELECT statement with it. I was wondering if I could do something like this:

DATA:

          line(200) type c,

          list like table of line(200).

 

LOOP AT parameters_from_sel_screen.

     IF parameter_n is not initial.

          CONCATENATE 'field_n =' parameter_n INTO line SEPARATED BY space.

          APPEND line to list.

          CLEAR line.

     ENDIF.

ENDLOOP.

 

SELECT * FROM table

WHERE (list).

Thank you in advance for your help.
