Hello everybody,

i need to solve the following problem:



data: l_structure type DFIES-FIELDNAME,
      ls_outtab type ref to data,
      lt_outtab type ref to data.
fieldsymbols: <lt_outtab> type standard table,
              <ls_outtab> type any.


l_structure = 'ZZ_TEST'.
* The DDIC Structure ZZ_TEST has 2 fields: A and B both CHAR10.


* Table
create data outtab type standard table of (l_structure).
assign outtab->* to <lt_outtab>.


* Workarea
create data ls_outtab type (l_structure).
assign table field ls_outtab->* to <ls_outtab>

The question now is, how can i assign the workarea <ls_outtab> a value to its field A and to its field B?

The codeline "<ls_outtab>-A = 'xyz'" gives me a syntax error.

best regards

Markus

Hi!

You can do it by::

FIELD-SYMBOLS: <field> TYPE ANY.
ASSIGN COMPONENT 'SOME_FIELDNAME' OF STRUCTURE <ls_outtab> TO <field>.
* do whatever you want with <field>

If you want to append fields to your table, you can do:


FIELD-SYMBOLS: <field>     TYPE ANY,
               <ls_outtab> TYPE ANY.
APPEND INITIAL LINE TO <lt_outtab>.
READ TABLE <lt_outtab> ASSIGNING <ls_outtab> INDEX sy-tfill.
ASSIGN COMPONENT 'SOME_FIELDNAME' OF STRUCTURE <ls_outtab> TO <field>.
* do whatever you want with <field>

Note that you don't need to hassle with typing - both your <ls_outtab> and <field> can be TYPE ANY.

Hope this helps.

Regards,

Igor

Hello Markus,

After the statement <b>assign outtab->* to <lt_outtab>.</b> in your code, you can do the following -

loop at <lt_outtab> assigning <ls_outtab>.

" do your processing using <b>assign component of</b>

endloop.

Hello,

thanx to for very fast answers

What i want to do is assign content to the different fields of the structure <ls_outtab> and then append this content to the table <lt_outtab>.

so at runtime <ls_outtab> has 2 fields A and B. I want to add content to field A and to field B. Then i want to append this new line to table <lt_outtab>.

regards,

Markus

Thanx Igor,

your lines


APPEND INITIAL LINE TO <lt_outtab>.
READ TABLE <lt_outtab> ASSIGNING <ls_outtab> INDEX sy-tfill.
ASSIGN COMPONENT 'SOME_FIELDNAME' OF STRUCTURE <ls_outtab> TO <field>.
* do whatever you want with <field>

are working great Thanx!

Markus,

This is exactly what my suggestion is doing. Have you tried it? Here it is, once again, a little bit modified to make it more clear:


FIELD-SYMBOLS: <field>     TYPE ANY,
               <ls_outtab> TYPE ANY.
APPEND INITIAL LINE TO <lt_outtab>.
READ TABLE <lt_outtab> ASSIGNING <ls_outtab> INDEX sy-tfill.
ASSIGN COMPONENT 'A' OF STRUCTURE <ls_outtab> TO <field>.
<field> = 'Value of the field A'.
ASSIGN COMPONENT 'B' OF STRUCTURE <ls_outtab> TO <field>.
<field> = 'Value of the field B'.

Regards,

Igor

Sorry, I guess we were typing at the same time. I'm glad it works.
