ASSIGN_TYPE_CONFLICT error is coming

Question

Hi,
I am facing problem when Loop at Field Symbol is executing. In first one block Loop to work area is giving dump and in second one it is showing error in Assign statement where char value to internal table assign statement has written.
Please find the code below.
Thanks in advance.

Jyoti

Hi jyoti,
< ASSIGN (l_tname) TO <fs_icatsd>. >
You can not assign the values to the internal table directly, instead you need to assign the values to the work area and then
append that work area in to an internal table.  Even i am not getting your question clearly, i am just giving one example here..
For example:
types:begin of typ,
          example type c length 25,
          end of typ.
data: l_example TYPE char25 VALUE '(SAPLCATS)ICATSD[]'.
data: itab type ref to data,
         wa type ref to data.
FIELD-SYMBOLS: <fs_itab> TYPE STANDARD TABLE,
<fs_wa> TYPE any,
<fs_val> TYPE any.
CREATE DATA itab TYPE TABLE OF typ.
ASSIGN itab->* TO <fs_itab>.
CREATE DATA wa TYPE typ.
ASSIGN itab->* TO <fs_wa>.
*here the sy-index is 1 field position of example
ASSIGN COMPONENT 1 OF STRUCTURE <fs_wa> TO <fs_val>.
if sy-subrc = 0.
<fs_val> = l_example.
endif.
append <fs_wa> to <fs_itab>.
then you can loop this table now.
