Hi,

If you have the instance of the class then you need to use

CALL METHOD instance->if_interface~method_name (

EXPORTING

IMPORTING ).

thanks

here the case is like this

data :

lv_type TYPE REF TO IF_some xyz.

now by using a static class method i am able to get the return type equal to lv_type i.e

CALL METHOD cl_someclassname=> amethod ( )

IMPORTING

type = lv_type.

now when i debug and see lv_type is having a class name inside it. I want to use a method of this class.

How can I call the method which Iam able to see in the lv_type when i debug.

Hello

You need to cast your interface object to the corresponding class object:

data :
lv_type TYPE REF TO IF_some xyz,
lo_class TYPE REF TO cl_xyz_class.  " implements interface IF_SOME_XYZ

now by using a static class method i am able to get the return type equal to lv_type i.e

CALL METHOD cl_someclassname=> amethod ( )
IMPORTING
type = lv_type.

lo_class ?= lv_type.
CALL METHOD lo_class->name_of_method.
