Question details

The user needs to hide the "No Value" group header that automatically appears when grouping tasks by an outline code that lacks assigned values.

How to Hide No Value Groups in Microsoft Project Views

Product: Microsoft Project
Device & OS: not provided
Scenario: Organizing and categorizing tasks in a project view using outline codes for reporting or tracking.
Observed behavior: Microsoft Project displays a persistent "No Value" group header for tasks without assigned outline code values, which cannot be hidden natively while the grouping is active.

Before you start

Ensure you have permission to modify custom fields, filters, and outline codes within your Microsoft Project file, as the workarounds involve creating new data columns.

Solution 1Recommended

Use a Custom Filter and Flag Field

Since the group header cannot be hidden natively while grouping is active, replacing the grouping with a custom Flag filter is the most effective way to hide unassigned tasks.

This method involves creating a dedicated field to identify the tasks you actually want to display, thereby bypassing the automatic 'No Value' grouping behavior.

Add a Custom Flag Field

Right-click a column header in your project view, select 'Insert Column', and choose a custom 'Flag' or 'Number' field (e.g., Flag1) from the dropdown list.

Mark the Relevant Tasks

Go through your task list and change the value in your new Custom Flag field to 'Yes' (or a specific number) for all the tasks you want visible in your view.

Remove Default Grouping

Navigate to the 'View' tab on the ribbon and clear the current grouping settings that are causing the 'No Value' headers to appear.

Apply a Custom Filter

Create and apply a new filter from the 'View' tab that only displays tasks where your Custom Flag equals 'Yes', effectively filtering out the blank or unassigned items.

Clean Project View: Using a filter instead of grouping guarantees that tasks with empty outline codes are entirely removed from your visual display without deleting them from the project.

Solution 2

Assign a Placeholder Value to Blank Items

If you must keep the grouping active, giving the empty outline codes a discrete placeholder value allows them to be grouped cleanly.

Frequently Asked Questions

Why does Microsoft Project automatically show a 'No Value' group?

This occurs whenever you apply a grouping based on an outline code or a custom field, and one or more tasks in your project schedule do not have a value assigned for that specific field.

Can I permanently delete the 'No Value' group header in MS Project?

No, Microsoft Project does not provide a native setting to permanently hide or delete the 'No Value' header while a grouping feature is actively enabled. You must use workarounds like filtering or assigning placeholder values.

Will filtering out 'No Value' tasks affect my project calculations?

No. Hiding tasks via a filter only changes your current visual view. It does not delete the tasks from the database, meaning your overall resource allocations, durations, and schedule calculations remain completely intact.

How do I create a new Custom Field for filtering in MS Project?

Right-click any column header, select 'Custom Fields', choose 'Flag' or 'Number' from the type dropdown, and rename it to suit your needs. You can then insert this new column into your view to start marking tasks.
