Problem:

Maps fail to generate with Internal Error: Unable to access Transaction Map reference.

Resolution:

1. Start a SOA project (I called it Test)

2. Skip the section where you specify the .PRJ and just hit next.

3. Once the project was created (should not have the screens right now) I went to the Project dropdown and selected "Import eBiz transaction.

4. I browse the .mpr file you attached and added it to the project. Once you open the .mpr, the information should be generated "Import eBiz" screen.

5. Press OK and the project is imported.

6. Validate the eBiz and run the generation.
