Generic CLASS parameters

Former Member — Wed, 12 Dec 2007 08:58:04 GMT

Hi,

I have a function module with a TABLE parameter with generic type TABLE.

I have to pass these table parameter to a method in the class, then what should be the type of the corresponding parameter inside my class.

Regards,

Anoop

STANDARD TABLE should work from a function module table param. Otherwise ANY TABLE

If your function module table parameter is "mytab", you may have to call the method using mytab[].

As if now i had passed mytab from fn mod to the method.

Now i have to assign it to a class attribute

Could u please guide me to create a class attribute with generic type to assign this value.

[I have tried to create a class attribute with type STANDARD TABLE but it shows error msg like Generic type not possible for class attribute...]

Ah, you can't create a generic class attribute. But you can create a data reference to a generic object.

Instead of creating an attribute "mytab", create an attribute that is a reference to data,e.g. ref_mytab, of type REF TO DATA.

In your method, where you've received the table through the parameters (e.g. it_mytab TYPE STANDARD TABLE ), do this:

GET REFERENCE OF it_mytab INTO ref_mytab.

Whenever you need to do something with the table, do this:

FIELD-SYMBOLS: <mytab> TYPE STANDARD TABLE.
ASSIGN ref_mytab->* TO <mytab>.
