Table parameters question

Former Member — Wed, 18 Jun 2008 15:39:29 GMT

Hi all,

I want to pass a table as a changing parameter in a few different subroutines. I define the table using a type and a couple of data statements as follows:

TYPES: BEGIN OF t_user,

bname TYPE ubname,

tid TYPE utid,

END OF t_user.

DATA: gt_users TYPE STANDARD TABLE OF t_user.

I then define the method signatures as follows:

FORM retrieve_users CHANGING pt_users TYPE table.

FORM retrieve_user_auth CHANGING pt_users TYPE table.

In the first subroutine I do an append of rows to an empty table. In the second subroutine I attempt a modify on a populated table. Problem is the second subroutine balks when I perform a check. It seems it doesn't like the general table type declared in the method signature. Any thoughts on how to over come this problem?

Thanks,

Mat

Hi,

TYPES: BEGIN OF t_user,

bname TYPE ubname,

tid TYPE utid,

END OF t_user,

tab_user type standard table of t_user.

DATA: gt_users TYPE STANDARD TABLE OF t_user.

I then define the method signatures as follows:

FORM retrieve_users CHANGING pt_users TYPE tab_user.

FORM retrieve_user_auth CHANGING pt_users TYPE tab_user.

Thanks,

TYPES: BEGIN OF t_user,

bname TYPE ubname,

tid TYPE utid,

END OF t_user.

TYPES: ty_t_users TYPE TABLE of t_user.

data: gt_users type table of ty_t_users.

FORM retrieve_users CHANGING pt_users TYPE ty_t_users.

If you want to pass tables using 'USING' or 'CHANGING', the table must be of a TABLE TYPE.

When you declare your table using:

DATA: gt_users TYPE STANDARD TABLE OF t_user.

You're creating an internal table typed to a structure, not of a table type.

Regards.

Declare table type and use that in the changing parameters.

Like:


types: ty_t_user type table of t_user.

FORM retrieve_users CHANGING pt_users TYPE ty_t_user.

FORM retrieve_user_auth CHANGING pt_users TYPE ty_t_user.

I have done few changes in ur code. Pl. check.

TYPES: BEGIN OF t_user,

bname TYPE ubname,

tid TYPE utid,

END OF t_user.

types: my_table type standard table of t_user.

DATA: gt_users TYPE my_table.

perform retrieve_users CHANGING gt_users.

perform retrieve_user_auth CHANGING gt_users.

FORM retrieve_users CHANGING pt_users TYPE my_table.

endform.

FORM retrieve_user_auth CHANGING pt_users TYPE my_table.

endform.

Hi,

You need to define a table type and then use it in FORM signature

FORM retrieve_users CHANGING pt_users TYPE tt_tabletype.

Thanks
