can you explain to me why this is an exception path?

if there is any issue that may arise from any report email to another department and trying to solve any discrepancies could be a different use case i can creation i considered although what you said absolutely makes sense but can i show a seperate use case showing all the interaction between business and that department.

what about when the other department creating the ticket after getting an email from business user, who is the primary actor( business user or the other department)? do you think that is also another exception path as well or i can make this a seperate use case scenario like identify reports with error and act regarding to that such as creating a ticket and so on?

Thank you.

Dear M Islam: 

You have given a good text description of your project / assignment but that is NOT sufficiently clear for Use Case modeling. 

It is not clear what the TO BE PROCESS IS and WHAT functions / services are assigned to the System to be developed.  It is NOT clear if there is ONE System for NA and NB or multiple Systems.  Based on TO BE PROCESS MAP shown in BPMN or UML Activity Diagram A USE CASE DIAGRAM must be created separately for each System.  Then one can proceed to Use Case Descriptions of each Use Case.

KIMBO seems to be an experienced Analyst but I am not sure that a new professional like you can make good use of his inputs.

I would be glad to provide systematic and rigorous training for Use Case Modeling to you and other professionals / users.  The first session over Skype will be free.  Then you can decide if you wish to proceed with my proposed training.  I estimate that it would require 4 to 5 Sessions of 60 to 90 mnts each.  email to [email protected] for details.  Best wishes,
