Calling SAP Transactions from WDA

[phanir_mullapudi]

There are people who still want to know if it is really possible to Call a Transaction/T-code from a WebDynPro ABAP application.

I put together a quick set of steps to help answer that. We will call the HUPAST transaction in SAP.

1) Create a WD application ZTEST_CALL_HUPAST.

2) In the main View, create a button "HUPAST".

3) Create an OnAction event handler method CALL_HUPAST & place the below code in it.

method ONACTIONCALL_HUPAST .

DATA lo_window_manager TYPE REF TO if_wd_window_manager.
DATA lo_api_component  TYPE REF TO if_wd_component.
DATA lo_window         TYPE REF TO if_wd_window.

lo_api_component  = wd_comp_controller->wd_get_api( ).
lo_window_manager = lo_api_component->get_window_manager( ).
lo_window         = lo_window_manager->create_external_window(
                   url = 'http://ersbxdb0.gene.com:8040/sap/bc/gui/sap/its/webgui?~transaction=*hupast'
                   ).
lo_window->open( ).

endmethod.

4) Create a WD Application for this component, Activate component & run the URL.

RESULT: Once user hits the HUPAST button, It will create a new window with the HUPAST transaction. You can replace the transaction with any of your choice.
