Class types multi level table

[Former Member]

Hello everyone

I need to create a type in a customized class that will be used to have multi level table.

The first type is the structure of the final table. Inside that structure there is a field that is type table of string:

TYPES: BEGIN OF ty_data,
        Extension TYPE CHAR04,
        Delimiter TYPE CHAR01,
        line      TYPE TABLE OF string,
       END OF ty_data.
       
TYPES: lt_data TYPE TABLE OF ty_data.

The problem is when I am creating the TYPE ty_data, the system give me the following error message.

"You cannot use generic type definitions within structures"

Is anyone have an idea on how I can have that king of structure definition inside a class?

I even try to have something like:

TYPES: ty_string TYPE TABLE OF string.
TYPES: BEGIN OF ty_data,
        Extension TYPE CHAR04,
        Delimiter TYPE CHAR01,
        line      TYPE ty_string,
       END OF ty_data.
       
TYPES: lt_data TYPE TABLE OF ty_data.

That doesn't work either.

any suggestion?

Hi,

I tried this.

TYPES: ty_string TYPE TABLE OF string.

DATA : BEGIN OF ty_data,

extension TYPE char04,

delimiter TYPE char01,

line TYPE ty_string,

END OF ty_data.

TYPES: lt_data LIKE TABLE OF ty_data.

And it worked.

Hello Prasenjit

Thank you for your answer.

But it will not work. We cannot use "LIKE" in unicode programming into a class.

But I found the solution. I need to use an already existing table type

types: BEGIN OF TY_DATA,
           extension   TYPE CHAR04,
           delimiter   TYPE CHAR01,
           lines       TYPE SCR_STRINGS,
       END OF TY_DATA .

The type SCR_STRINGS exist into the SAP dictionary.

Now I can create a variable that is:

DATA: lt_data TYPE TABLE OF ty_data.
