Call WebUI application in NWBC via Citrix from external application

Hello experts,

I have the following issue, I need to generate an email link to a Web Dynpro Application.

In the past, I successfully did this using a SAPGUI link to a transaction, for example CV03N (Display Document).

CALL METHOD document->add_attachment

            EXPORTING

              i_attachment_type    = 'SAP'

              ...

Now, I want to have this feature in NWBC. The problem is the link is automatically opened in Internet Explorer.

Is there a way to create this in ABAP/4?

Also, I don't have NWBC installed locally, instead it is available on Citrix.

Please point me in the right direction as I'm clueless on how to achieve this.

Thank you!
