Internal table as a class attribute

Former Member — Wed, 09 Mar 2005 12:21:26 GMT

Hello everybody.

I think many of you hhave passed through the same problem. I have a requirement to pass internal table to class as for example class constructor parameter. It is desirable that class should get the table of variable structure.

How coult that be realized?

Thank you in advance for your kind help.

Best regards,

Andrey

*---------------------------------------------------------------------*
class lcl_app definition.

  public section.

    methods: constructor importing table type table.


endclass.



*---------------------------------------------------------------------*
*       CLASS lcl_app IMPLEMENTATION
*---------------------------------------------------------------------*
*       ........                                                      *

As mentioned earlier, you can TYPE the parameter as a generic table type, for example TYPE STANDARD TABLE, TYPE INDEX TABLE, etc.

Your next problem is how to use the table. You can create a work area with a DATA statement:

DATA:

wa_table LIKE LINE OF parameter_table.

You can:

LOOP AT parameter_table INTO wa_table.

Since your code does not know the field names, you must

access the fields by assigning to a field symbol using:

ASSIGN COMPONENT index OF ... TO ...

Is this what you need?
