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 : com.wm.app.tn.err.EXMLException:

wm.tn.doc:relateDocuments

com.wm.app.b2b.server.ServiceException

In your code are you using wm.tn.doc:relateDocuments? 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?
