Calling WebDynpro input screen from within an abap Function module / user

[Former Member]

Hi,

I am posting SAP data with a BAPI from an Web Dynpro Application.

In the Bapi I must use an BADI/User -EXIT to add some infornation.

Today this is done by calling an Dynpro in a function module. This creates a pop up, data is filled and posted on commit.

How can I get a Web Dynpro application to display this popup without showing the "call screen without connection " error ?

Thanks for any help.

Here is an unofficial way to get current WD component.

(WDR_TASK class is not for customer)

DATA lo_wdr_component TYPE REF TO cl_wdr_component.

lo_wdr_component = wdr_task=>application->component.

then.. attach component usage and popup your WD screen

BUT IT'S NOT OFFICIAL!!

This approach is absolutely NOT supported nor recommended by SAP.

You can't. BAPIs (and all inner implementation including BADIs) must run dark (without User Interface). This is espeically true when called from Web Dynpro, BSP or within a Web Service.
