Start with the account, workspace, project, and schedule shown in the top bar. Many apparent data problems come from opening a different file or leaving a filter active.

I can’t edit a schedule

Check these in order:

1. Access: a shared schedule or Project Viewer role is read-only. Editing normally needs Editor or Admin access.
2. Mode: switch from View to Edit. Look in More actions if controls are hidden by window width.
3. Lock: an imported P6 file may be locked. An authorized editor must unlock an ordinary working file before editing.
4. Version: a child version is a preserved snapshot. Copy it for independent editing; use other file actions only where offered. Published update logic stays read-only.
5. Archive or progress stage: restore an archived file where appropriate, or check whether the cycle is still collecting or has completed.
6. Account capability: personal editing requires paid access; team roles have license requirements. An inactive workspace may need its Owner to resolve billing.

A disabled control can also mean the selected row is a WBS or the field is calculated/inapplicable. Read the message next to the action. See Roles and access and Schedules and versions.

A project or schedule is missing

Confirm the invited email address and workspace. Use Library to search across your accessible work, or Files within the known project. Clear filters, enable archived files, and expand parent schedules to find versions.

A direct schedule share does not grant access to every project file. Ask the owner to confirm the intended share or project membership. Do not create duplicate projects merely because the current account cannot see the existing one.

Activities are missing

Clear the schedule’s filters, check Spotlight’s row-filtering option, expand WBS/groups, and confirm the active schedule. Check the visible-versus-total count and search by Activity ID as well as name.

If a custom-field filter is active, blank values may exclude the activity. Match all versus Match any can also change the result substantially. Turning off a filter does not undo data edits; it only reveals rows.

If the activity was removed from the plan, compare with an earlier file or inspect History rather than assuming the view is responsible.

My edits did not appear to save

Commit the cell or finish the dialog, then check for an error or pending operation. Ordinary schedule edits save as committed; calendar, view, and print-layout dialogs have their own save/apply controls.

Save As creates a schedule version or copy. Save view preserves presentation settings. Apply in Filter activates the drafted filter. These are different operations.

Before refreshing after an error, keep a note of the affected values. If the problem persists, report the file, activity, field, and error message to support. Do not assume a failed request succeeded because the value appeared briefly in the grid.

Dates changed after calculation

Check status date, actuals, remaining duration, calendar exceptions, relationships, lag, constraints, and calculation mode. A direct date edit can change constraints or duration; a date at/before the status date can be interpreted as actual progress.

An import can initially show source dates, then produce different forecast dates when Syncify calculates using its supported model. Resource leveling, external relationships, unsupported constraints/options, or MPP calendar differences may explain the change.

Use Calculate a schedule, Details, Driving Path, and a pre-calculation version to investigate.

A duration does not match the calendar-day span

Working duration excludes nonworking nights, weekends, breaks, and exceptions. Check the assigned activity calendar and its hours. Summary/dashboard spans or variances can use calendar-day differences, so they need not equal activity working duration.

Lag uses the predecessor’s calendar. The viewer’s timezone should not shift the schedule’s project dates. See Calendars.

An activity says 100% but is not completed

Physical percent is a manual measure and does not set completed status or calculate remaining duration. Record actual completion explicitly. A progress collection showing 100% updated only means the reporting tasks have responses.

Check which percentage you are viewing: physical, duration, activity-count completion, and update-completion percentages have different meanings.

Import fails or information is missing

Use P6 XER or Microsoft Project MSPDI XML/supported MPP. P6 XML is not supported. For an unsupported or password-protected MPP, export an unprotected XML from Microsoft Project.

Read warnings and calendar errors. Verify the original source file; changing its extension does not convert it. Some source fields and scheduling behaviors are intentionally outside the supported import coverage.

See Import a schedule, P6 compatibility, and Microsoft Project compatibility. Send support the error and file type when a supported file still fails.

Progress entry or Submit is unavailable

The project must be Premium and belong to a team workspace. Contributors need Editor or Admin access, and the cycle must be Collecting. Only Admins can initiate, apply, return, cancel, or publish a cycle.

For Required rows, review Update Start, Update Finish, milestone type, and the cutoff. A start alone may not finish the response. For a blocked Submit, inspect the remaining list, including other assignees and unassigned activities. Do not enter guessed actuals to clear the count.

Use Submit a progress update or ask the manager to review the cycle stage.

Dashboard history or metrics are missing

On Files, check the Current schedule, Baseline designation, Update # tags and their order, and each file’s status date. Import or preserve the historical files if they do not exist yet.

Some metrics need a baseline, an earlier reporting window, matching activities, or a nonzero population. A blank result is not necessarily zero. The Overview quality card shows a saved score, so check its profile and whether a fresh run is needed.

See Project dashboards before changing source data to address an apparent chart problem.

A comparison shows unexpected additions and deletions

Confirm the newer and older selections. Check whether activity identities or IDs changed in the source, or whether the schedules describe different scopes. Renaming an activity and recreating it are not necessarily equivalent for matching.

For repeated submissions, maintain source identity and consistent IDs. Inspect a few known activities before drawing conclusions from the change totals. See Compare schedules.

A PDF is blank, too small, or missing work

Check the selected schedule and view, filters, collapsed groups, timeline window, page size, orientation, and print layout. Inspect the preview before generating the file.

Reduce unnecessary columns or date span before forcing a large schedule onto one page. If generation completed but nothing opened, check browser downloads. If it failed, record the error and try a simpler known view/layout to isolate the problem.

See Print and export.

Someone cannot open a share link

Check the signed-in email, invitation status, link expiration, domain restriction, and whether the link has been revoked. An ordinary copied page URL does not grant access. A schedule-only share does not allow editing or all-project browsing.

Ask someone authorized to review Manage schedule access or project Team. See Sharing.

I still need help

Use Contact support in the docs navigation. Include the workflow, schedule name/ID, relevant Activity IDs, the error text, what you expected, and a screenshot if it helps. For date differences, include the status date and calculation mode. Account and support explains the form.
