Attachement Details (GOS) in Web Dynpro (ABAP)

Question

I posted this question in the Web Dynpro ABAP forum and got no response, so I'm moving it here:
We are developing a Web Dynpro application to display PO attachment details (PDF file etc).
In the corresponding R3 application, we use FMs ARCHIVE_GET_CONNECTIONS and ARCHIV_DISPLAY_LIST_2. They work perfectly.
The Web Dynpro application uses both FMs but one of them returns an error "Screen output without connection to user". This is returned from FM K_KKB_LIST_DISPLAY which is trying to popup a screen.
So we would like to know if we are going about this correctly or if we should be using different FMs.
Thanks for any insight you can provide.

Answer 1

Have you checked the fm  ALINK_DOCUMENTS_DISPLAY
This is program documentation found in the initial source of function module
* Description:
* Display a single document using one of the following ways of
* communication:
* - display via CMOD SALIN001
* - display via ArchiveLink_internal exit
* - Wingui
*    - OLE automation
*    - display URL document via OLE start (only HTTP interface)
*    - HTML - Control (only HTTP interface)
*    - separate Browserwindow (only HTTP interface)
*    - EAI  - Control (only HTTP interface)
*    - Mix scenario: first get the document on the client PC, second
*      display local file
*    - R/3 (printlists)
* - HTML-GUI
*    - HTML - Control (only HTTP interface)
*    - separate Browserwindow (only HTTP interface)
*    - R/3 (printlists)
*  - Platinum GUI
*    - R/3 (printlists)
*    - not supported for other documents
PS : CL_GOS* class will not work in WebDynpro, i think these are using control framework.
May this will help you out.
