Using a generic object

Question

I would like to be able to create an instance of an ABAP object without knowing the object type first. for example, if a specific type of message hits a queue, create a handler object specific to that message. I need to be able to declare the object variable as something not strongly typed, and do the create object for whatever actual object i want to use. I have checked the docs, but found nothing.

Hi David,
I think this feature can be achieved only in WAS 6.40. ( Someone correct me here, if I am wrong ).
This syntax is available, perhaps only in 6.40 WAS, and didn't work in 4.6C.
CREATE DATA dref TYPE HANDLE <class_name>.
Since, I do not have 6.40 WAS, I will give a shot-in-the-dark solution:
data: lv_variable(25) type c value 'CL_GUI_ALV_GRID'.
data: myref type ref to data.
field-symbols: <FS> type any.
assign lv_variable to <fs>.
if sy-subrc = 0.
  create data myref type handle <fs>.
endif.
I do not guarantee this will work, but with the document link, which Shehryar Khan has given in the previous post, I am guessing this should work.
If it works, then you can create an object at runtime, of any classname.
