No, it is NOT. Currently, classes do not support dynpros directly. However, you can call function modules, which can call dynpros. But you CAN NOT call dynpros directly in a class method.

HI Rich,

From which version is this new change for i have developed a program of late, which does call a screen from a method of a class.

Regards,

Ravi

sample code:

report zexample.

*button to be clicked after which the event should get triggered

selection-screen: pushbutton /10(20) button user-command but1.

initialization.

button = 'LISTS'.

----

CLASS cl_names DEFINITION

----

class cl_names definition. " declare the events in this method

public section.

class-events: get_event exporting value(fcode) type sy-ucomm.

class-methods: user_action.

endclass. "cl_names DEFINITION

----

CLASS fcode_handler_class DEFINITION

----

class fcode_handler_class definition. " definition for handler events

public section.

methods: fcode_handler for event get_event

of cl_names importing fcode.

endclass. "fcode_handler_class DEFINITION

----

CLASS cl_names IMPLEMENTATION

----

class cl_names implementation. "Raise the event

method user_action.

raise event get_event exporting fcode = sy-ucomm.

endmethod. "USER_ACTION

endclass. "cl_names IMPLEMENTATION

----

CLASS fcode_handler_class IMPLEMENTATION

----

class fcode_handler_class implementation. "implement the handler event

method fcode_handler.

case fcode.

when 'BUT1'.

*WRITE: 'Hello Program !!'.

*message i001(zz) with 'Test'.

<b>call screen '0100'.</b>

endcase.

endmethod. "fcode_handler

endclass. "fcode_handler_class IMPLEMENTATION

data: h1 type ref to fcode_handler_class.

*start-of-selection.

at selection-screen.

create object h1.

set handler h1->fcode_handler." FOR ALL INSTANCES.

call method: cl_names=>user_action.

Call to the screen highlighted and is working fine.

Hi Ravi,

in your example you are using local classes. I want to use Dynpros in global classes which are created with the Class Builder (SE24).

Thanks Rich for your response. Is there any documentation for your solution?

That is a local class implemented in a report progam, hence it is allowed, with global classes it is not.
