Using components of unknown table

Former Member — Wed, 24 Oct 2007 12:28:56 GMT

Hi,

I have a form where I work with an unknown table. What I know is, that every table that is given to the function has i.e. the component PERNR. I want to do some things with these components (sorting the table, putting into another table etc.) but whether I use field symbols or data references I get the error that it has no structure (which is right).

For more specific information:

My tables are P2001 - P2012 (which is nice to work with, hence the numbers).

I want to pass a specific table of these to the form, but the form should treat them all the same (only in some special cases where I use a case on the string which contains the table).

If you have a solution please help me. I read most of the stuff about field symbols and data references so a short answer would help too.

Thanks in advance, Christopher

you can try like this -


PARAMETERS: dbtab TYPE c LENGTH 10, 
            rows  TYPE i DEFAULT 100. 

DATA dref TYPE REF TO data. 

FIELD-SYMBOLS: TYPE ANY TABLE, 
               <wa>    TYPE ANY, 
                 TYPE ANY. 

TRY. 
    CREATE DATA dref TYPE STANDARD TABLE OF (dbtab) 
                          WITH NON-UNIQUE DEFAULT KEY. 
    ASSIGN dref->* TO  . 
    SELECT * 
           FROM (dbtab) UP TO rows ROWS 
           INTO TABLE  . 
    LOOP AT  ASSIGNING <wa>. 
      DO. 
        ASSIGN COMPONENT sy-index 
               OF STRUCTURE <wa> TO . 
        IF sy-subrc = 0. 
          WRITE / . 
        ELSE. 
          EXIT. 
        ENDIF. 
      ENDDO. 
      ULINE. 
    ENDLOOP. 
  CATCH cx_sy_create_data_error. 
    WRITE 'Wrong Database!'. 
ENDTRY.

Hope it helps.

Thanks, this helps a lot.

In addition I will need the function 'DDIF_NAMETAB_GET' because I recognized that the component names are only similiar, not equal.
