Problem with populating internal with field-symbol

Question

hi all,
      I have following structure of internal table .
internal Table 1(int1) : source,source_field, and other fields.
internal Table 2 (int2): x1,x2,x3,x4,x5,x6 .
Read table 1 assigning <gs_t1> with....
assign ( <gs_t1>-source_field ) to <ld_char> .
case <gs_t1>-source.
when 'int1'.
     Read int1 assgining <gs_int1> .
      ASSIGN COMPONENT <ld_char> OF STRUCTURE <gs_int1>
      TO <fs_char>.
wa_output-x1  = <fs_char>.
simillarly,
  ASSIGN COMPONENT <ld_char> OF STRUCTURE <gs_int1>
      TO <fs_char>.
wa_output-x2  = <fs_char>.
The source_field of int1 contains any value either it can be x2,x3,x4 .
Now the problem is how my work wa_output should know that <fs_char> contains value of field x1 .
I mean to say how  we willl determine that value to be passed is to  wa_output-x1 or  wa_output-x2  as <ld_char> is just a pointer we cannot determine anything .
so how should i make my workarea . It can be made as a fields-symbol but how to that .
As it is having a strucutre of like :
componenet       component_type
CONTROLLER     PRXCTRLTAB<-this is also a line type having value two fields
x1                        char5
x2                        char5
Plz help...

Answer 1

Hi all,
i have to pass all field values after obtaining them to a workarea wa_output .
data : wa_output type xyz.
READ TABLE ist_smp_tst ASSIGNING <gs_smp_tst>
                      WITH KEY iden_no =
                     <gs_smp_tst_dtl>-iden_no
                      BINARY SEARCH.
        ASSIGN COMPONENT <ld_char_val> OF STRUCTURE
        <gs_smp_tst_lab> TO  <fs_char>.
        CONCATENATE 'WA_OUTPUT-' <fs_char> INTO l_field.
        ASSIGN (l_field) TO <wa_field>.
        <wa_field> = <fs_char>.
   read table ist_temp .........
<wa_field> = <fs_char>.
I have done this but <wa_field> actually holds the current data of <fs_char>
it should be like
wa_ouput-f1 = <fs_char>..
                          wa_output-f2 = <fs_char>.
     and the appending it to wa_output to i_output .
How we can do this using field-symbol.
Plz required help.
Regards.
