Internal table

Former Member — Tue, 21 Feb 2006 17:54:12 GMT

Hi there,

How can I declare an internal table into another internal table type?

I'm trying this, but it's not working:

Textos

begin of ty_linhas ,

linha(255) ,

end of ty_linhas ,

begin of ty_textos ,

rsnum TYPE resb-rsnum ,

rspos TYPE resb-rspos ,

linhas type ty_linhas ,

end of ty_textos .

thanks,

Alexandre Nogueira

Textos

TYPES: begin of ty_linhas ,

linha(255) ,

end of ty_linhas ,

GT_LINHA TYPE STANDARD TABLE OF TY_LINHAS

begin of ty_textos ,

rsnum TYPE resb-rsnum ,

rspos TYPE resb-rspos ,

linhas type GT_linhas ,

end of ty_textos .

Now the field LINHAS of type TY_TEXTOS is a table with the same structure of TY_LINHAS

Hi ,

Try this.

Textos

begin of ty_linhas ,

linha(255) ,

end of ty_linhas ,

types : begin of ty_textos ,

rsnum TYPE resb-rsnum ,

rspos TYPE resb-rspos .

include type ty_linhas.

Types: end of ty_textos .

my code is this, the same the first message that I wrote

Textos

begin of ty_linhas ,

linha(255) ,

end of ty_linhas ,

begin of ty_textos ,

rsnum TYPE resb-rsnum ,

rspos TYPE resb-rspos ,

linhas type ty_linhas ,

end of ty_textos .

The error ir here

the error is: You cannot use generic type definitions within structures.

Are you trying to do this


TYPES: BEGIN OF ty_linhas,
        linha(255).
TYPES: END OF ty_linhas.

DATA: BEGIN OF ty_textos,
        rsnum  TYPE resb-rsnum,
        rspos  TYPE resb-rspos,
        linhas TYPE ty_linhas.
DATA: END OF ty_textos.

or this?


TYPES: BEGIN OF ty_linhas,
        linha(255).
TYPES: END OF ty_linhas.

DATA: BEGIN OF ty_textos,
        rsnum  TYPE resb-rsnum,
        rspos  TYPE resb-rspos,
        linhas TYPE TABLE OF ty_linhas.
DATA: END OF ty_textos.

Both are ok.

instead of TYPe use LIKe

linhas <b>LIKe</b> ty_linhas ,

Ok Sri, It really works, but this way, it's no longer a TYPE, it have become an object "ty_textos"

u can also use like this

DATA : BEGIN OF TY_TEXTOS,
         RSNUM TYPE RESB-RSNUM ,
          RSPOS TYPE RESB-RSPOS ,
          <b>BEGIN OF TY_LINHAS ,
            LINHA(255) ,
          END OF TY_LINHAS,</b>

END OF TY_TEXTOS .

Check this out

types: begin of t_tab4,

setid type t800s-setnr,

arbpl type crhd-arbpl,

charg type mseg-charg,

end of t_Tab4.

types: begin of t_tab3,

setid type t800s-setnr,

arbpl type crhd-arbpl,

charg type mseg-charg,

t_tab2 type t_tab4,

end of t_Tab3.

data: l_Tab3 type t_Tab3.

You define local types in your program to whatever complexity you want. You can have a simple type like

TYPE matnr(18). You can have a complex type like


TYPES: BEGIN OF ty_linhas,
        linha(255) OCCURS 10.
TYPES: END OF ty_linhas.

DATA: BEGIN OF ty_textos,
        rsnum  TYPE resb-rsnum,
        rspos  TYPE resb-rspos,
        linhas TYPE TABLE OF ty_linhas.
DATA: END OF ty_textos.

Here your type itself is a internal table and the structure that you later created is creating a complex field called 'linhas' which is an internal table of internal tables.

Type by itself cannot become an object holding data, unless it is used in the declaration of a data variable define using DATA statement.

I hope it is clear.
