Call one WDA from another

[Former Member]

Hi all,

I need to make some communication between two WD componenets.

I have two WD applications. I need to display a screen of one application in a pop up of another application. How would I do this?

Also, when a screen from second application is called I need to pass some parameters to it.

Please let me know if you've ever faced this need.

Thank you.

Hi,

you can execute any method of the component-B using this code in component-A:

DATA: l_ref_INTERFACECONTROLLER TYPE REF TO ZIWCI_PROJECT_DISPLAY .

l_ref_INTERFACECONTROLLER = wd_This->wd_CpIfc_Display( ).

l_ref_INTERFACECONTROLLER->Get_Project( PROJID = pid ).

Here Get_Project( ) is declared in the methods of the Interface controller. And this Get_Project( ) method is implemented in the component-B. In Get_Project( ) you can directly access the context of Component-b. And ZIWCI_PROJECT_DISPLAY is ABAP interface of the Interface controller created.

This is the way we can access the context of component-B from component-A. Hope I am clear..

Hi Pavikiran,

Thanks for the reply.

You say that I can access <b>context</b> of one component from another.

However, I need to display the whole screen of component A in component B.

Thank you.

You can use a view container in your layout and simply include the component A as a used component. Very similar to the way you use Select-options or the ALV components in your WDA applications.
