See if it helps:
 
DATA: dy_table TYPE REF TO data,
      dy_line  TYPE REF TO data.
FIELD-SYMBOLS: <dyn_table> TYPE STANDARD TABLE,
               <dyn_wa>,
               <dyn_field>.

*  ASSIGN dy_table->* TO <dyn_table>.
* Create dynamic work area and assign to FS
*  CREATE DATA dy_line LIKE LINE OF <dyn_table>.
*  ASSIGN dy_line->* TO <dyn_wa>.

  LOOP AT <dyn_table> INTO <dyn_wa>.
    DO.
      ASSIGN COMPONENT  sy-index
         OF STRUCTURE <dyn_wa> TO <dyn_field>. 
      IF sy-subrc <> 0.
        EXIT.
      ENDIF.
      IF sy-index = 1.
        WRITE:/ <dyn_field>.
      ELSE.
        WRITE: <dyn_field>.
      ENDIF.
    ENDDO.
  ENDLOOP.

Hi Kiran
 
Thanks, but what I'm doing is the other way around I think.
 
I have some SAP code that has already read a table in to <fs>, <fs> is
an object ref (lh_int_tab->*<fs> , call function using <fs>.. etc)
 
What I want to do is take the contents of <fs> and copy them in to a
normal internal table (standard table), when I try I get a short dump
stating that the conversion is incompatible.
 
How do I read the contents of the data object reference table in <fs> in
to an internal table?
 
 
Kind Regards
Sunni

This code snippet helps:
 
DATA: BEGIN OF line,
         col1(1) TYPE c,
         col2(1) TYPE c VALUE 'X',
       END OF line.

FIELD-SYMBOLS <fs> LIKE line.

ASSIGN line TO <fs>.

MOVE <fs>-col2 TO <fs>-col1.
WRITE: <fs>-col1, <fs>-col2.
 
 
By the way, using SE38 we can refer to the following list of demo
reports:
 
DEMO_FIELD_SYMBOLS_ASSIGN_COMP Assigning a Structure Component by
Component to a Field Symbol
DEMO_FIELD_SYMBOLS_ASSIGN_DECI Cast Decimal Places
DEMO_FIELD_SYMBOLS_ASSIGN_ERR  Data Areas for Field Symbols
DEMO_FIELD_SYMBOLS_ASSIGN_TYPE Cast with Predefined Data Types
DEMO_FIELD_SYMBOLS_CASTING     Casting Using Field Symbol Type
DEMO_FIELD_SYMBOLS_CASTING_TYP Casting Using Explicit Type
DEMO_FIELD_SYMBOLS_DYNAMI_AS_1 Dynamic ASSIGN
DEMO_FIELD_SYMBOLS_DYNAMI_AS_2 Dynamic ASSIGN
DEMO_FIELD_SYMBOLS_DYNAMI_AS_3 Assigning Field Symbols
DEMO_FIELD_SYMBOLS_STAT_AS_OF2 Static ASSIGN Using Offset
DEMO_FIELD_SYMBOLS_STAT_AS_OFF Static ASSIGN Using Offset
DEMO_FIELD_SYMBOLS_STAT_ASSIGN Static ASSIGN
DEMO_FIELD_SYMBOLS_STRUCTURE   Forcing a Structure on a Field Symbol
DEMO_FIELD_SYMBOLS_TYPE        Specifying the Full Type of a Field
Symbol

Here it is:
 
  DATA name(20) TYPE c VALUE 'ITAB-FIELDNAME'.
  FIELD-SYMBOLS <fs> TYPE ANY.
  ASSIGN (name) TO <fs>.
  IF sy-subrc EQ 0.
    WRITE / <fs>.
  ENDIF.

Hi
 
I'm integrating a workflow analysis report i've written into another
report.  This other report selects data from a database and puts it in
to a data reference object i.e.:
 
* assign data reference to table field symbol
  ASSIGN lh_paa_tab->* TO <fs_paa_tab>.
 
-> then a subroutine pulls back the data in to <fs_paa_tab>.
 
 
Now my traditional abap report starts with an internal table whick
matches <fs_paa_tab> structure.
 
I want to transfer the contents of  <fs_paa_tab> in to my internal table
so I can start my processing, but if I try I get a short dump because of
incompatibility.
 
How do I transfer the data from this data reference to a standard
internal table?
 
Any suggestion would be greatly appreciated.
 
Kind REgards
Sunni
