Testing:

To test this Business Network Definition in the Test tab on the playground or in your Angular app:

1- In the Customer, ServiceProvider, ServiceVendor participant registry, create new participants with appropriate input values.

Alternatively, you can also use the SetupDemo tranaction which would populate the network with 2xCustomers, 2xServiceProviders, 2xServiceVendors.

2- Creat a ticket using the Submit Transaction button and fill in the information based on the created participants. Upon submission, you should see a new asset added to the asset lists under 'TroubleTicket'.

4. SLA Back & Front-End

The following figure shows the Participants in the app and the process of creating them.
