You can tell clients more about the Request resolution by publishing the values of custom attributes.
For example, a developer wants to report what must be done to resolve the problem stated by the client. For this, add a custom attribute "Resolution steps" in the development project. For these steps to appear in the Request completion email, go to Administration - Settings - Texts and create a custom template for the email "ServiceDesk: Request status change notification", for example as follows:
The template function showattribute gets the value of the custom attribute for the Request (issue). The custom attribute name can be specified either by the display name or by the reference name.
