pass value of "ucomm" in ALV to a screen

[former_member182371]

Hi,

in my ALV i use this method:

METHOD handle_user_command." Handleown functions defined in thetoolbar

CASE <b>e_ucomm</b>.

WHEN 'CHANGE'.

PERFORM change_details.

WHEN 'INSERT'.

PERFORM insert_record.

WHEN 'DELETE'.

PERFORM delete_record.

ENDCASE.

ENDMETHOD.

within the different routines shown (e.g. insert_record) i call a screen.

<u>How can i get the value of e_ucomm once i am within the screen (PBO or PAI)?</u>.

hi,

i´ve declared e_ucomm as a global variable and it does not work either.

The program and the screen are in the same program.

i use this class:

CLASS lcl_event_receiver DEFINITION DEFERRED.

*----

-

---

• C L A S S E S

*----

-

---

CLASS lcl_event_receiver DEFINITION.

PUBLIC SECTION.

METHODS:

handle_toolbar FOR EVENT toolbar OF cl_gui_alv_grid

IMPORTING

e_object e_interactive,

handle_user_command FOR EVENT user_command OF cl_gui_alv_grid

IMPORTING

e_ucomm

.

ENDCLASS.

Best regards.

Hi calsadillo

Within the implementation of <i>handle_user_command</i>, assign <i>e_ucomm</i> to a global variable.

<u>e.g.</u>

DATA gv_ucomm_alv LIKE sy-ucomm .
...

METHOD handle_user_command .
...
gv_ucomm_alv = e_ucomm .
...
ENDMETHOD .

In fact, I recommend to encapsulate the ucomm as an attribute within the handler class, however the above way will solve your question in a classical approach.

Hi,

Try this out

SET HANDLER o_eventreceiver->handle_user_command FOR o_Alvgrid.

Hi Calsadillo,

In the code snippet you have shown above, contrary to what I suppose you're assuming, <b>e_ucomm</b> is not declared as a global variable.

For the variable to be global, you have to declare it outside the class definition. That is because, you want to use that variable Outside the objects of that class - i.e., <i>in the PBO of the next screen</i>.

The code given above by Serdar does exactly that. try to implement it and see if you still run into any problems. Get back if you do.

As long as you e_ucomm is moved to a global variable or it itself is declared as a global variable and your screen processing logic is also in the same program as your ALV program, you should be able to just use that value.

Are your ALV program and your screen program different or are they same?

Hi,

Why nor simply use a global variable where you save the UCOMM code?

Hope that helps (please reward me if it does),
