I tried to look in the DTR for open activities and there are couple of them still open by other Users. I am unable to view then under Open Activities. How can I close these open activities ?

Vijay.

Hi,

Check out this Article:

http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/70ee5ab2-8d7a-2c10-d88b-dbe2fdf66...

Check NWDI/JDI System Copy Prerequisites

Step 3 tells you how to handle the activities.

Hope this helps.

Hi Pramod,

Thank you. I was able to revert and delete the open activities checked-in by other Users.

However, I am still unable to Re-import the DC's and the same error persists.

Is there any clue why this error is still there ??

Regards,

Vijay.

Hi,

Try this once and see if you can reimport the track in NWDS.

In NWDS go to Window - Preferences - Expand Java Development Infrastructure - Development Configuration - See the Root Folder.

Go to the root folder location and delete the .dtc folder.

Close the NWDS and open it again and try to import the track and see if it works.

Not sure why NullPointerException occurs in this situation.

Hope this helps.

Cheers-

Hi Pramod,

Thanks a ton. Solved my problem.

Now I'm able to remove Configuration and Re-import also.

Vijay.
