A calendar displaying change schedule along with change tasks

[YamunaRaniK]

Hi All, I need help on creating a change schedule to be as a calendar displaying schedule changes based on their planned start and end dates along with associated change tasks. Here I am able to get changes like show in attachment but not the change tasks. How could I achieve it. please refer attached doc. Help on this is very much appreciated.

I ran into this same issue recently — where the Change Schedule calendar only showed the parent Changes but not the related Change Tasks. The fix is actually pretty simple. You just need to add another schedule source for the change_task table in the same calendar configuration.

Here’s what worked for me:

1. Go to System Scheduler → Schedule Pages, and open the page that’s being used for your “Change Schedule.”

2. In the Schedule Sources related list, click New and create one for Change Tasks.

   • Table: change_task

   • Start date field: start_date (or planned_start_date — depends on your instance)

   • End date field: end_date (or planned_end_date)

   • Name / Display template: something like ${number} - ${short_description} (Parent: ${change_request.number})

   • Color: pick something different from your main Change entries (so you can tell them apart easily).

   • Add a quick condition like State is not Closed or Cancelled so it only shows active ones.

Once you save this, you’ll now see both the Change Requests and Change Tasks on the same calendar view — plotted according to their planned start and end dates.

If you want to take it a step further, you can even color-code tasks by state (like red for overdue, green for in progress) or use tooltips to show extra details such as parent change number or assignee.

Hope that helps — this setup makes it a lot easier to visualize both changes and their related tasks in one place!

You can view Change records on the Change Schedule in the Calendar View based on their Planned Start Date and Planned End Date.

The Change Tasks (CTASKs) associated with a Change record will only be visible if they also have their Planned Start and Planned End dates populated.

Once these dates are filled in, you’ll notice a downward arrow next to the Change record on the Change Schedule.
By clicking that arrow, you can expand the record to view the related Change Tasks beneath it.

only these change tasks CTASK0010007 and CTASK0010013 are visible on the calendar view.

Hi Sneha,

Please see the attached.

 I have filled the change task planned start and end date within the time range of Change, still I am not getting that task under the change in schedule.

Help me with this query.

Hi @YamunaRaniK 

It’s an OOTB (Out of the Box) functionality, so there’s not much to do. However, make sure that the change task has both planned start and end dates defined.

Please check the change schedule definition and make sure you add the change task to the related list; otherwise, it will not work."
