Doubts using Assign statement in perform

Former Member — Tue, 23 Jun 2009 16:36:35 GMT

Hi Experts,

Im having some doubs in order to use assign in a dynamical perform. This is the cenario:

I have 3 tables of the same structure and in a routine they all go to the same perform, and will update the same internal table. I want that the perform be a little dynamic.

Th problem it's that for each internal table, the field to be update it's diferent, and i want to know if it's possible to do what i want using the assign statement. I've allready tried, and the code example goes with my test , but it's not working because instead of update the table field that i want move the value to the field symbol..

Here goes an example of the code:


....
**Docs 41
  CLEAR: str_valor, str_num.
  str_valor = 'TAB_LISTA-VALOR_41'.
  str_num = 'TAB_LISTA-NUM_DOCS_41'.

  PERFORM get_values TABLES tab_docs USING str_valor
                                         str_num.

*Docs 61
  CLEAR: str_valor, str_num.
  str_valor = 'TAB_LISTA-VALOR_61'.
  str_num = 'TAB_LISTA-NUM_DOCS_61'.
  PERFORM get_values TABLES tab_61 USING str_valor
                                         str_num.
.....
.....
....

FORM get_values TABLES   p_tab STRUCTURE tab_docs
                USING    p_valor
                             p_num_docs.

  DATA lv_bankl TYPE t012-bankl.
  DATA lv_hkont TYPE t012k-hkont.
  DATA lv_banks TYPE banks.

  FIELD-SYMBOLS: <valor> TYPE ANY,
                 <num_docs> TYPE ANY.


  ASSIGN: p_valor TO <valor>,
          p_num_docs TO <num_docs>.

  LOOP AT p_tab.
    CLEAR: lv_bankl, lv_hkont, lv_banks.

    MOVE: p_tab-hkont TO lv_hkont,
          0 TO lv_hkont+9(1).

*Determinação de Banco  - Descritivo
    SELECT SINGLE f~bankl f~banks INTO (lv_bankl, lv_banks)
      FROM t012 AS f INNER JOIN t012k AS g
      ON f~bukrs = g~bukrs
      AND f~hbkid = g~hbkid
      WHERE g~hkont = lv_hkont
      AND g~bukrs = pa_emp.

    SELECT SINGLE banka FROM bnka INTO tab_lista-banco
           WHERE bankl = lv_bankl
           AND banks = lv_banks.


**Calculos para os documentos 41
    MOVE: p_tab-hkont TO tab_lista-conta.

    WRITE p_tab-dmbtr TO <valor>. "This is where the field to be updated differs

    AT NEW belnr.
      MOVE 1 TO <num_docs>. "This is where the field to be updated differs
    ENDAT.

    COLLECT tab_lista.
  ENDLOOP.
ENDFORM.

Can anyone help me on this subject??

Thanks in Advance,

Best Regards,

João Martins

Hi,

Here I see some problem on your coding:

Your original coding is:


ASSIGN: p_valor           TO <valor>,
              p_num_docs   TO <num_docs>.

The coding should be:


ASSIGN: (p_valor)         TO <valor>,
              (p_num_docs) TO <num_docs>.

In your Subroutine try like this:


  ASSIGN: (p_valor) TO <valor>,
          (p_num_docs) TO <num_docs>.

I assume that TAB_LISTA is the global table in your program.

Hi,

Based on what conditions the updatation of the fields differ? If you want to update the table using field-symbols then better while creating the field-symbols refer them to one of the internal table structures as all the internal tables have same structure. It will be easy to refer to the fields using <fs> else you can not do <fs>-field when the <fs> is being referenced to TYPE ANY. Hope this is clear.

Let me know on what conditions you are going to modify the internal table, please.

Thanks & Regards,
