The current behavior of Hyperlink is that it redirects user to the place from where the user launched the Smart Reporting. If cross launch happened from Mid Tier, the hyperlinks redirect to Mid tier and similarly for Smart IT.
At present there is no way to configure this as a user choice.
Additional question: How can we create our own hyperlinks for ID fields?
Where are they exactly created and how? Is there any documentation available?
In case you wish to go to old IT Home instead here is a format for the incident in IT Home.
1.Just create a calculated field in the report and that's it.
Note that you need to use parser first by adding the first part, then field etc. I have to say that parser needs some work for better editing capabilities
2. Additionally you need to do a bit of formatting of the column itself. Same logic will apply to Changes and Work Orders and possibly SmartIT too in case you cannot get the parameters working.
