Hi Nalla,
As Kiran said, there is a data element mismatch in context node.
To find out where the issue is originated, you can use your short dump from ST22.
- Place an external break point at point where the exception has occurred.
- Run the application and once the debugging point is reached
- Use the standard tab in debugging window and use the call stack to go backward and find the right step
Please refer the snapshot of debugging window.
Hope this helps you.
Regards,
Rama
