Access to R/3 Transaction from Web Dynpro Application with parameters.

[SantiMoreno]

Hi Gurus.

I have a question from a customer in which he asks whether I can access to a SAP transaction from a Web Dynpro App I've implemented.

I followed thru a document I found about how to do it (but nothing about parameters); so, I've generated an external window (explorer) which accesses to the demanded URL (let say http://customer_server/sap/bc/gui/sap/its/webgui/?~transaction=FB03).

Is there any way to access that transaction giving information to the entry fields (BELNR, GJAHR and BUKRS)? I was going to use SET ID Params but since it's a new session, no info is passed.

Kind Regards.

Santy.

Hi Santiago,

Use the following code to call SAP Transaction from web dynpro abap and passing values to it.

DATA lo_el_context            TYPE REF TO if_wd_context_element.
 DATA ls_context                TYPE               wd_this->element_context.
 DATA lv_vbeln                   LIKE                ls_context-vbeln.
 
 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.
 
 DATA lv_url                       TYPE        string.
 DATA lv_host                    TYPE        string.
 DATA lv_port                     TYPE string.
 
 lo_el_context = wd_context->get_element(  ).
 
 lo_api_component = wd_comp_controller->wd_get_api( ).
 lo_window_manager = lo_api_component->get_window_manager( ).
 
 lo_el_context->get_attribute(
 EXPORTING
 name =  `VBELN`
 IMPORTING
 value = lv_vbeln ).
 
 * Call below method to get host and port
 
 CLEAR : lv_host , lv_port.
 
 cl_http_server=>if_http_server~get_location(
 IMPORTING
 host = lv_host
 port = lv_port ).

 '/sap/bc/gui/sap/its/webgui/?sap-client=&~transaction=*VA02%20VBAK-VBELN='
 lv_vbeln
