Web Dynpro ABAP call transaction in the foreground

Question

In Screen Painter/SAP ALV, we can create a screen where for example if you double click on a sales order field it can take you a VA03 transaction by :
call transaction VA03 ... and skip first screen.
I am creating Web Dynpro ABAP application that needs to do the same thing where if we click on the field, it will take to VA03 transaction or other transactions.
Has anyone done this in Web Dynpro ABAP? I have done some research and determine that we cannot call transaction in the foreground? I hope I am wrong.  Any help/insights will be greatly appreciated.

Hi Phong,
WDA is generic client to Netweaver connection based on HTTP/S.
At this stage on a few clients are supported. WEB dynpro client and Browsers...
SAPGUI connects to SAP using a different protocol.
No SAPGUI connection is implied by a WDA client connection.
Therefore  abap statements that invoke screens and otherwise assume SAPGUI
is connected are not supported in WDA.   eg call screen, call transaction
You can either
                     a) build your own WDC to front end calls to BAPIs to get the Sales order data.
                    b) open/ exit to the new WDC for Sales Orders in ERP2005
                          see LORD_MAINTAIN_COMP
                       c) exit to the INTERNAL ITS URL for transaction VA03 
                           eg http://<host>:<port>/sap/bc/gui/sap/its/webgui?~Transaction=VA03
                          but getting the skip first screen may require you to call custom tran ZVA03
                           which calls VA03 to skip first screen setting the PID appropriately.
Hopefully you opt for option a) or b).
c) can work... I have used it from BSPs but it not pretty.
