Roundtrip Model Elements to DOORS

This guide provides instructions for roundtripping Model Elements from Enterprise Architect to DOORS using ReqXChanger.

Create Traceability Links in Enterprise Architect

In Enterprise Architect, links can be created from Model Elements to Requirements using Dependencies.
This can be performed in a Model browser or in Diagrams.
In addition, Stereotypes can be applied to the Dependencies to distinguish different kinds of links.
Any Model Elements like Use Cases, Classes, Operations, Attributes, States and Diagrams can be linked to Requirements.
Furthermore, indirect links can be created, for instance between a Test case and a Class, which has a Dependency to a Requirement.

Roundtrip Model Elements

Information about all Model Elements, which have a Dependency on a Requirement, can be transferred to DOORS.
This is also valid for Diagrams that are linked to Requirements.

• In ReqXChanger, select the roundtrip mode by clicking the button at the bottom left of the interface:
  
  
  
• In ReqXChanger, run the roundtrip mode by clicking the Read, add Links and Write button:
  
  
  This will create a connection with Enterprise Architect, to create a ReqIF File to import into DOORS.

Import and Merge Model Elements into DOORS

To import Model Elements:

• In DOORS select the menu File > Import ReqIF Package, and select the roundrip reqifz file created by ReqXChanger.
  It is located in the same folder as the ReqIf file used to import Requirements, and is called "xxx_RXCRoundtrip.reqifz".
• Set a name to the New import folder.
• Select the Import button.

To merge imported Elements:

• Select the ReqIF Definition previously created (to export Requirements).
• Select the Imports button.
• Select the Merge button. DOORS will automatically merge the Requirements and Model Elements.
  
  
  
• Select the Close and OK buttons to close the ReqIF import wizard.
• In DOORS Module, you will see that the Requirements have inlinks to a new Module called "EA Elements":
