Using a string for a column name for an internal table.

Hi All,

I need a little help if possible, I have searched for the solution but no luck, what I have found out though is I probably need to use field symbols...

Basically I need to use a string as a column name to access an internal table.

I think maybe an example would be good.


    DATA: lw_field(30)   TYPE c,
        lw_cname(30)   TYPE c,
        lw_tab_ref(60) TYPE c,
        lwa_cust_x     LIKE LINE OF i_cust_x.
    
  FIELD-SYMBOLS: <fs> LIKE LINE OF i_cust_x.

  IF w_exit_exec IS INITIAL.
  " No missing madatory so far
    LOOP AT i_cust_x INTO lwa_cust_x.
        IF lwa_cust_x-ekorg = space.
        " Check for blank Purch Ord
            IF lwa_cust_x-zesokz = fuwa_data-zesokz.
                IF lwa_cust_x-xman = 'X'.
                " Mandatory import item


                   lw_cname = lwa_cust_x-field.
                    TRANSLATE lw_cname TO LOWER CASE.
                    CONCATENATE 'fuwa_data-' lw_cname INTO lw_tab_ref.
                    ASSIGN lw_tab_ref TO <fs>.
                    IF <fs> = space.
                            lw_field = lwa_cust_x-field.
                            w_exit_exec = 'X'.   "DON'T PERFORM UPDATE
                            MESSAGE i045 WITH lw_field INTO fcw_message.
                            EXIT. 
                    ENDIF.


                ENDIF. " Mandatory import item
            ENDIF.
        ENDIF. " Check for blank Purch Ord
    ENDLOOP.

  ENDIF. " No missing madatory so far

I was hoping that after the assignment <fs> would be a reference to the fuwa_data with the column of what has been from lwa_cist_x_field....

but it seems that <fs> is a reference to a string in fact lw_tab_ref

so lets say that

lwa_cust_x-field = 'EKORG'

lw_cname='ekorg' after the translate

fuwa_data has a column called ekorg

<fs> = fuwa_data-ekorg (but is a sting)

I would like to say something like...

IF <fs> = 1000 THEN " as in accessing the column in fuwa_data and not a string...

......

I hope I have explained this ok, but I am having trouble finding the best example.

Cheers

Ian

Hi,

please use brackets for the assign command.


ASSIGN (lw_tab_ref) TO <fs>.

Kind Regards,

Dirk

Hi,

I think what you need is

ASSIGN COMPONENT lw_cname OF STRUCTURE fuwa_data TO <fs>.
