The Schedule menu is enabled by default for the program and all the projects within. If you want to disable schedules for the entire program, you may do so using this tab.

Additionally, you can create custom data fields that will display along with other task settings.

To disable schedules: 

1. Access the Program.
2. From the side nav menu, select Configuration. 
3. Click on the Program Items menu item and then Schedule.
4. Click on Enable Schedule toggle to turn it off.
   You have now disabled the Schedule menu. Users will no longer be able to view it in the project's top menu strip.

 

To define custom fields mapped to tasks:

Ensure that schedule is enabled for the program.

1. Access the Program.
2. From the side nav menu, select Configuration. 
3. Click on the Program Items menu item and then Schedule.
4. Click on the Task Properties button.
   This will display the Properties tab.
   
5. Use the options to create new custom fields and map globally available custom fields to the tasks within your program.
