Hi Supriya,

I was looking for this only and now it needs to looked by your basis team. There is no need to look into from code or application side.

This issue is from JCO Destination side.

Hi Supriya,

First go to protal content, and under this try to find our the iview and then you will get the WebDynpro name.

Go to SE80 and use the WebDynpro name here to execute this.

Please let me know if you need any further information.

Thanks,

Hi Supriya,

Can you please first specify the type of WebDynpro (Java or ABAP)?

Thanks,

Thanks,

Hi Supriya,

There is no TCode for Java WebDynpro. Please try to run this java WebDynpro application without portal so you will come to know that this problem is happening due to portal or in webdynpro itself.

If you find that application is behaving in the same way as in portal then you have to take the code and create the project in NWDS and do debugging to reach to the root cause.

Please let me know if you need any more information.

Thanks,

Hamendra

Hi Supriya,

As I mentioned in my previous post that you should talk to your basis guys about code repository. I hope you guys shall be using NWDI.

You have to take your code from DI and then create the project.

By the time you get the code, try to run this application directly (without portal) to understand exactly where is the problem.

First you confirm about your webdynpro code.

Thanks,

Hamendra

Hi Supriya,

The best way to go further from this point is of checking log file. If you are on Netweaver 7.0 then go to Visual Admin and if above this then go to NWA and check the log. In log you will definitly get some expections or errors.

Please copy that log here as well.

Thanks,

Hamendra

Hi Hamendra,

Basis person have checked the log there are no related logs.

Hi Supriya,

Is basis Guy checked default.trc file in J2EE server? It can't happen that there is no error recorded in log file.

Thanks,

Hi Supriya,

Are you sure the above two screenshots (1 from QAS & 1 from PRD) are of the same application?

Because those two application names appear to be different.

Moreover, as Hamendra has suggested, try to look for the errors in the logs and traces.

You can also go for debugging option to understand the application flow and to crack down the issue.

If you've NWDI installed, you can also create a dummy activity and transport the working version of your development code from DEV to QAS.
