Why do equipment activity records show as overdue even after changing the Task Due Date?

This article is applicable only through Grand Avenue 15.4. In the 15.5 release, the ability to change the task due date on an equipment activity task was removed and a feature allowing activity due dates to be changed was added.

At releases 15.5 and later, activity due dates can be changed by clicking Manage Equipment Activity Records > Manage Incomplete Activities > [select one or more pieces of equipment] > Change Due Date for Selected Activities.

The short answer is that the dates are different because they are associated with two separate items within Grand Avenue.

In Equipment Management, the due date of an incomplete activity such as calibration and the due date of the associated task that authorizes the assignee to complete the activity are separate, independent dates.

Activities (for example, calibration) are associated with a piece of equipment. An equipment activity record contains information such as the equipment ID, the activity type, and the activity due date. GAS currently prohibits the Due Date on an equipment activity record from being changed. Initially, the Activity Due Date and Task Due Date are identical.

The task associated with an incomplete activity authorizes the assignee to complete the activity. A task contains information such as the task name, the assignee, and the task due date.

Now change the original Task Due Date of 09-Nov-2020 to 25-Nov-2020. While it’s possible to delay the task from becoming overdue by updating the task due date, that doesn’t change the fact that the maintenance activity was due on 09-Nov-2020 based on the schedule in place when the incomplete activity record was generated. The screen shot shows the equipment Activity Due Date is unchanged and the Task History table shows the updated Task Due Date, along with an asterisk indicating the date was updated.

Similarly, the Task Due Date change appears in the View Task Assignment page, along with a table showing the history of any changes made to the Task Due Date.

If a piece of equipment is temporarily not needed and won’t be replaced (or calibrated) until immediately before it goes back into use, the intended behavior is that its status be changed from “In Service” to a status that suspends activity scheduling (See Configure Equipment Management > Configure Equipment Status Values).

If the equipment status is changed (e.g. to “Out of Service”) before the equipment reaches its scheduling window, no incomplete activity record or associated task will be generated. If the equipment status is changed (e.g. to “Out of Service”) after an incomplete activity record and associated task have been created, the incomplete equipment activity record can be withdrawn. No further incomplete activities will be generated until you return the equipment status back to “In Service.”
