Finding Late Tasks with Microsoft Project Custom Filters

When managing a project schedule of even a moderate size, it’s valuable to be able to quickly identify late tasks without scrolling through a large hierarchy of tasks. In Microsoft Project, you can identify incomplete, late, or slipped tasks by using one of these options:

  • Tracking Gantt view
  • Incomplete Tasks filter
  • Late Tasks Assigned to Resource filter
  • Slipped/Late Progress filter

These built-in filters are nice, but I usually need to filter on a different set of criteria to view the data I like to see. So I decided to create a custom filter in Microsoft Project that would identify late tasks.

Finding Late Tasks the Easy Way

My original approach was to identify a late task by filtering on the % Complete field, the Baseline Finish, date, and the Resource name column. I followed these steps:

1. Select the Tracking Gantt View using the Entry Table.
2. Insert Baseline Start and Baseline Finish.
3. Confirm the % Complete column is in the view.
4. Filter on the % Complete column (Figure 1).

5. Filter on the Baseline Finish date where the Baseline Finish Is Less Than Or Equal To a given status date (Figure 2).

The resulting schedule identifies all the tasks that haven’t finished and can be filtered by resource (Figure 3).

This approach worked to generate a list of late tasks for project status reviews; however, once I switched views or needed additional information, I had to remove the filter and then rebuild it a few minutes later. This process quickly became tiresome to simply view late tasks. The need for a quick and reusable filter to identify tasks that were behind schedule led me to create a custom filter that I named Behind Schedule.

Finding Late Tasks the Easier Way:  Behind Schedule filter

You can create your own custom Behind Schedule filter by following these steps:

1. Select Project | Filter For | More Filters and click New.
2. Enter “Behind Schedule” in the Name field.
3. Click the first row in the Field Name and select the Baseline Finish field.
4. Enter “is less than or equal to” as the test condition.
5. Enter “Status Date:”? into the Value field (Figure 4).

(It is important to enter the question mark after the quote value, as this represents a parameter. The text entered between the quotation marks is the actual text that will appear in the dialogue box.)

6. Click the second row and select the % Complete field.
7. Select the “does not equal” Test condition and enter 100% as the value in the Value column.
8. Click the OK button (Figure 5).

Using the Behind Schedule filter

To use the filter, click the Behind Schedule filter in the Formatting toolbar and select the Project Status date. The filter will identify any incomplete tasks based on a selected date (Figure 6).

To clear the filter, click the All Tasks in the Filter combo box, and all the project tasks will display.

Three key points about using the filter

1. Remember to baseline.
In order for the filter to work, you need to baseline (gasp) the project schedule. If project teams are hesitant to baseline the entire schedule, you should apply a rolling planning approach and baseline the tasks for the next phase or major milestone.

2. Look at Slipping Tasks.
The Behind Schedule filter identifies only tasks that are incomplete and have exceeded the baseline finish date. I encourage you to also look at the Slipping Tasks and Slipped Tasks\Late Progress to identify tasks with impacted start dates.

3. Add the filter to your Global.mpt file for future projects.
The Behind Schedule filter that you created is a local filter that is available only in the current .mpp file. If you want this filter to be available for all your projects, you need to add the filter to your Global.mpt file, which contains all the custom objects for your Microsoft Project files.

To add a custom filter to your Global.mpt file, select Tools | Organizer | Filters, select the Behind Schedule filter, and click the Copy button (Figure 7).

    How do you filter or group Milestones per Month in MS-Project 2010???

  2. Darren Garner July 16, 2014 at 9:34 pm #

    Actually, How do you count the number of Milestones per Month and include percent complete as well???

    • Andrew Makar July 17, 2014 at 11:48 pm #

      I don’t have a specific tutorial on grouping the milestones by month. You may want to filter on all the milestones and export the milestone tasks, date and percent complete and then use Excel to calculate the milestones per month.

    Dear Andy,

    I’m working with MS Project Professional 2010.

    I want to build a single filter that can identify:
    a. ‘Late Tasks’ (based on the Project Status date) compared to the baseline, and,
    b. Tasks coming up in the next two weeks.

    Could you please tell me the fields I need to enter into a New Filter?

    I was hoping to be able to open the Late Tasks filter and the Date Range filter to see the field criteria and then simply copy both of them into new filter. But is seems I cannot open or edit filters in MS Project. is this true?
