bizdoc/GroupID issue

How bizdoc/GroupID will be generated when you send any file to TN. Is there any dependency on TN_parms for bozdoc/GroupID.

When i route a FF to TN the bizdoc/GroupID value should not be null. It was working fine but from last one day i am getting null value in bizdoc/GroupID.

Error message:

The original error was com.wm.lang.flow.FlowException: com.wm.lang.flow.FlowException :
“relationship” is required. “relationship” is required.

In your code are you using As the error indicates trying to relate documents (FromDoc/ToDoc bizdocs) and isn’t complaining about GroupID.

Could be GroupID issue for diff document or for routed FF.Can you review the issue closely?
