Error in displaying hierachry report with TableView and Tableiterator

Question

Hello,
I tried to create a BSP as shown in this tutorial:
/people/vijaybabu.dudla/blog/2008/08/04/display-hierarchy-report-in-bsp-using-tableview-and-tableview-iterator
When starting the BSP I get an error that a field symbol is not assigned in the method get_column_name.
When debugging the method get_column_name I can see that row_ref is initial. So the field symbols <row> and <col> are not assigned to any values, which causes the error some lines below.
METHOD get_column_value .
*-To get the Column values which is used in the Interator
  FIELD-SYMBOLS: <row> TYPE ANY, <col> TYPE ANY, <cur> TYPE ANY.
  ASSIGN row_ref->* TO <row>.
  ASSIGN COMPONENT column_name OF STRUCTURE <row> TO <col>.
  DATA tempchar(240) TYPE c.
  IF currency IS NOT INITIAL.
    ASSIGN COMPONENT currency OF STRUCTURE <row> TO <cur>.
    WRITE <col> CURRENCY <cur> TO tempchar.
    MOVE tempchar TO column_value.
    CONCATENATE column_value ` ` <cur> INTO column_value.
  ELSE.
    WRITE <col> TO tempchar.
    MOVE tempchar TO column_value.
  ENDIF.
  CONDENSE column_value.
ENDMETHOD.
Any help?
Thank you

Hi Patrick,
Thank you for the answer.
Unfortunately there is still the error with the unassigned field symbol after implementing the render_row_start method.
Any help?
Edit: It works now. There was an error with a wrong variable name (stupig mistake.)
Thanks for the help!
