SUBMIT Report from WDA on button action

Hi Gurus,

Before I could start my question, I have done fare amount of googling but I couldn't get exactly what I needed.

I need to do call below from button action from webdynpro.

EXPORT gs_planning TO MEMORY ID 'ABC'.

     SUBMIT zabc_launch VIA SELECTION-SCREEN AND RETURN.

I want to execute this report and open SAPGUI session on button action.  I dont want this to be embedded in WDA.

I tried with IView, which is not appropriate because it doesn't generates unique URL everytime. We have to use this across

different landscape which I feel IView is not an option.

Should I need to create ABAP tranx to call SAPGUI session from WDA? How I have approach this ?

Thanks in Advance!

Best Regards,

Vinod
