Customers are identified by contract and/or customer number and email address. Depending on the requirement, further characteristics, e.g., the meter number, can be incorporated.
Customer is uniquely identified:

The relationship between the ticket and the customer is marked in green.
Name, customer number, and contracts are correctly displayed.
Customer could not be uniquely identified:

The relationship between the ticket and the customer is marked in yellow.
Name, customer number, and contracts are displayed conditionally. Verification is necessary.
By clicking on “Ok”, the suggestion is accepted, and the relationship between the ticket and the customer is marked in green.

By clicking on “Review”, all links to the ticket can be removed or a new profile can be assigned.
With the subsequent search, the correct customer can be found and assigned by name, email address, contract number, or customer number.
If no relation can be established between the ticket and the customer, an “Unknown User” and a search field are displayed.
