Where to set up a TYPE-POOL Declaration in a Function Group ?

Question

Hi,
I ve got a Function Group.
I set up a Function Module in the Function Group.
I must use  TABLES I_T_SELECT TYPE SBIWA_T_SELECT.
I get the error:
Type pool SBIWA has not been declared
Message no. FL031
Diagnosis
You used a type from type pool & in the interface of a function module.
Procedure
For the program to be syntactically correct, you must
declare the type pool in the global data declaration of the
function group using the 'TYPE-POOLS: &.' statement.
Where / How do I set up a Type Pool in the global data declaration of the
function group ?
Where / what is the global data Declaration of the Function Group ?
Thank You
Best Wishes

Hello Martin,
First off:
TABLES I_T_SELECT TYPE SBIWA_T_SELECT.
Correct me if I'm mistaken here, but tables is expecting a name of a DDIC structure. It is then creating a work area using that structure.
If you have to declare an internal table, the correct code would be:
DATA i_t_select TYPE TABLE OF sbiwa_t_select.
Or:
TABLES sbiwa_t_select.
Regarding your questions:
A global data declaration of a function group is just what it says, a point where you can declare your data usable for the whole function group.
This is usually an Include.
That said, you can fix your issue by creating an Include in your function group.
Within that include you have to write:
TYPE-POOLS: pool1, pool2, pool3.
or, in case you only have one type pool:
TYPE-POOLsbiwa
After creating the include, you have to point your function module to that file.
INCLUDE include_name.
Kind regards,
