How to LOOP AT dynamic internal tables.

Question

I have an internal table name declared in field I_DYN_TAB with me and I want to loop at this I_DYN_TAB.
( 4 example:
DATA: I_DYN_TAB(10) VALUE 'I_TAB'.
where I_TAB is my internal table with data in it.)
I already tried couple of things.
A. READ TABLE (I_DYN_TAB) WITH KEY I_DYN_TAB-FIELD1
but, it is not allowing me to read it dynamically this way.
B. LOOP AT (I_DYN_TAB). Again this is also not working.
Another option I tried is to create a field symbol for the internal table, which again is not useful or may be I am doing it wrong.
So if anybody can help me in solving this problem, it would be great.
Waiting for reply.

U can use
ASSIGN COMPONENT...
Eg:
FIELD-SYMBOLS: <dyn_field>,
                 <dyn_field1>,
                 <dyn_field2>,
                 <dyn_field3> TYPE ANY .
* Test when UOM, 'KMEIN' is '%'
*        <b>ASSIGN COMPONENT 'KMEIN' OF STRUCTURE p_line1 TO <dyn_field1>.</b>
*        ASSIGN COMPONENT 'KBETR' OF STRUCTURE p_line1 TO <dyn_field2>.
*        ASSIGN COMPONENT 'KBETR' OF STRUCTURE p_line1 TO <dyn_field>.
* Test when Curr, 'KONWA' is '%'
        ASSIGN COMPONENT 'KONWA' OF STRUCTURE p_line1 TO <dyn_field1>.
        ASSIGN COMPONENT 'KBETR' OF STRUCTURE p_line1 TO <dyn_field2>.
        ASSIGN COMPONENT 'KBETR' OF STRUCTURE p_line1 TO <dyn_field>.
        IF <dyn_field1> = '%'.
          <dyn_field> =  <dyn_field2> / 10.
        ENDIF.
        if <dyn_field2> LE -1.
          <dyn_field> = <dyn_field> * -1.
        endif.
          INSERT p_line1 INTO TABLE p_output1.
Hope this helps.
