a) Please let us know whether you are using Web Dynpro for ABAP or Web Dynpro for Java.
b) Please check this useful document by Arun Bhat - https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/f3f93ee7-0c01-0010-2593-d7c...

Hi,
What you are trying to do in WD is not possible. This is what the note says:
<i>Reasons:
In the case of RFC communication between an R/3 system and an external program (for example, C, Visual Basic or other external programs), outputting screens or lists always terminates the communication, regardless of the user type, unless the external program has a SAPGUI available (RFC with SAPGUI).
Solution:
In the case of RFC communication between an R/3 System and an external program without function RFC with SAPGUI, the called R/3 function modules must be modified so that screens or lists are no longer output.</i>
So either you create a WD screen for this report or set up ITS and use a transaction iview.

Thanks Satyajit for consitent replies.
At the end what i learn is that :
1) Showing the abap screen on WD is not possible. For that i have to create contexts, take the values, and show it on iview using UI.
2) or going for ITS.
I already assigned u a points, but if i m wrong just correct me..

Hi,
You have tried to call an RFC through WD going via the standard route of creating models. But if your RFC returns a ABAP screen or shall I say, calls another report through ABAP "SUBMIT" call, then your WD model will simply fail. That's because the java model classes have no way to handle such an output.
So if you want to show some ABAP report/screen/transactions through WD, you should host them through ITS. That is the most standard way of doing this.
Regards,
Satyajit.
