Is it possible to create attribute in Z Class of type any

Question

Hi Friends,
I am working on a requirement to fine tune the code. for this i need to store the values retreived from a remote FM call in a global internal table. I am trying to check whether is it possible to create a global attribute of type any. This  would help me to use the same internal table for down processing also. other wise i need to create several gloabl internal tables with the required structures.
any pointers on this would be very helpful.
Thanks,
udaya

These generic types can only be used for field symbols and import / export parameters of methods and function modules. Here is a thought though: You can create some sort of container in which you can store all kinds of internal tables from your function module.
1. Create a global type in DDIC, or a local type in your class.
Code for local type:
TYPES: BEGIN OF ty_container,
         name        TYPE char30,
         container   TYPE REF TO data,
       END OF ty_container.
TYPES: tty_container TYPE SORTED TABLE OF ty_container WITH UNIQUE KEY name.
2. Create a private / protected attribute when using local type or any attribute you like when using a global type (set step 1).
3. Create a method (let's call it ADD_DATA) which imports the name of the structure the internal table from your FM is based on and the actual internal table. The import parameter for this internal table is typed TABLE (generic).
4. Coding in method:
  DATA: ls_itab TYPE ty_container.
  DATA: lv_data_ref       TYPE REF TO data.
  FIELD-SYMBOLS: <lt_value> TYPE table.
  CREATE DATA lv_data_ref LIKE ipt_itab.
  ASSIGN lv_data_ref->* TO <lt_value>.
  <lt_value> = ipt_itab[].
  ls_itab-name = itabname.
  ls_itab-container = lv_data_ref.
  INSERT ls_itab INTO TABLE gt_container.
Now the global attribute gt_container can hold any kind of internal table you add to it. It can be read using the NAME column field.
Hope this makes any sense to you, if not let me know.
BTW: Doesn't look like an ABAP Performance and Tuning issue (other forum).
