The Users see the error as in the screenshot because the user is not added to the Manage License list.

To track time in Salesforce using the Lighting Component, 

  • The TimeTracker user should be linked with Salesforce User 
  • The user must be added to the Manage Licenses list.

Linking the TimeTracker user with the Salesforce user: 

  • Log in to Salesforce as administrator, go to the TT users tab, click the new button, and enter user details like Name, First Name, Last Name, Employee ID, etc., Then link the user with their Salesforce user ID in the Salesforce User field. Select the "Allow Individual use, not team use" check box, and the user type "Individual user" and click the Save button.

Adding the user to the Manage Licenses list: 

  • Click on Setup and search for Installed packages, and click the Manage Licenses string for the PK4 TimeTracker app. Click the Add Users button and add the users that need access to the TimeTracker for Salesforce objects for tracking time.
