Dynamic programing

Former Member — Mon, 15 Sep 2008 13:58:31 GMT

I'm trying to load data from flat file. The first line of the flat file is the field names(header names).

I'm storing the field names into wa_header then dynamically reading the value of the field from w_infile.

My question is, can I get the internal table field names dynamically (i.e t_good-<fs_comp> = <fs_dat>).

Any help or suggestion is highly received.

below is my code:

INITIALIZATION.

CALL FUNCTION 'DB_GET_TABLE_FIELDS' "Returns the description of fields in a database table

EXPORTING

tabname = 'ZHR_INCENTIVE'

TABLES

dbfields = lt_dbfields.

LOOP AT t_infile INTO w_infile.

WHILE sy-subrc = 0.

IF sy-index = 1. CONTINUE. ENDIF. "Do not process index 1

*wa_header holds the table headers such field names.

ASSIGN COMPONENT sy-index OF STRUCTURE wa_header TO <fs_comp>.

READ TABLE lt_dbfields WITH KEY name = <fs_comp> INTO ls_dbfields.

ASSIGN COMPONENT <fs_comp> OF STRUCTURE w_infile TO <fs_dat>.

t_good-<fs_comp> = <fs_dat>. "This code is not compiling or working

ENDWHILE.

ENDLOOP.

Do like this.

DATA: gv_temp TYPE string.

FIELD-SYMBOLS: <fs_new> TYPE ANY.

CONCATENATE 'T_GOOD' <fs_comp> INTO gv_temp.

ASSIGN (gv_temp) to <fs_new>.

<fs_new> = <fs_dat>. " Here you can assign the value

I'm trying to move data to internal table daynamically. If you look my previous code you will see it. But I have problem getting internal table fields dynamically.

How can I get the internal table field name daynamicaly(t_good-<fs_comp>)?

ASSIGN COMPONENT <fs_comp> OF STRUCTURE w_infile TO <fs_dat>.

t_good-<fs_comp> = <fs_dat>. "This code is not compiling or working

Thanks

For that only I am telling. Do in the following way.

DATA: gv_temp TYPE string.
 
FIELD-SYMBOLS: <fs_new> TYPE ANY.
 
CONCATENATE 'T_GOOD-' <fs_comp> INTO gv_temp. " Add '-'
 
ASSIGN (gv_temp) to <fs_new>. " gv_temp will have T_GOOD-FIELD1
 
<fs_new> = <fs_dat>.  " Now T_GOOD(work area or hearder) will have the value <fs_dat>

APPEND T_GOOD. " Append the value to internal table

U need to use another field-symbols in order to move the data to structure:

LOOP AT T_INFILE INTO W_INFILE.

    WHILE SY-SUBRC = 0.
      IF SY-INDEX = 1. CONTINUE. ENDIF. "Do not process index 1

*wa_header holds the table headers such field names.
      ASSIGN COMPONENT SY-INDEX OF STRUCTURE WA_HEADER TO <FS_COMP>.
      READ TABLE LT_DBFIELDS WITH KEY NAME = <FS_COMP> INTO LS_DBFIELDS.

      ASSIGN COMPONENT <FS_COMP> OF STRUCTURE W_INFILE TO <FS_DAT>.

*     T_GOOD-<FS_COMP> = <FS_DAT>. "This code is not compiling or
* working

* U need another field-symbols:
     ASSIGN COMPONENT <FS_COMP> OF STRUCTURE T_GOOD TO <FS_TAB>.
     <FS_TAB> = <FS_DAT>.

    ENDWHILE.
  ENDLOOP.
