The fields can be set as mandatory using the TimeTracker configuration screen in Salesforce.
To make the fields mandatory,
- Go to the TT apps tab, click on the app name, and click the Config button,
- From the Check-in tab, click the Individual Check-In sub-tab, then select the fields if mandatory or optional and save the configurations.
Once you make the object mandatory, the user can check in only after selecting the Object in Salesforce, Mobile, Web, or the Google Chrome application.
Follow the same instructions to set up the fields as mandatory for the Team users. Go to the Team Check-in screen to set the object as mandatory for the team Check-Ins.
