Hiding tasks from the Gantt Chart
Have you ever wanted to hide tasks from the Gantt Chart? The following technique is useful for tidying up a schedule – for example, if you want to show only pertinent Gantt information for a presentation, or take a screenshot of a plan for a client that contains some internal tasks.
To hide individual bars in the Gantt display, simply insert the “Hide Bar” field and set it to “Yes” for the requisite tasks:
After hiding:
You’ll notice that all incoming dependencies for the hidden bar are also hidden, so take care when looking at your predecessor/successor logic!

Showing/hiding items from the Gantt Chart
A useful little nugget about Microsoft Project that came in handy the other day is showing or hiding items from your Gantt chart. It’s as simple as this:
In Microsoft Project right-click in the Gantt Chart and select “Gridlines”:
To show, for example the Current Date on your Gantt, select “Current Date” and change the line type from blank to any other line style. Change the colour if required, then click “OK”.
My example here is showing the Status Date as a red line, and the Current Date as a blue line:
Traffic light indicators for schedule
One query that we receive a lot from our clients is about setting up automatic traffic light (or RAG) indicators for their project schedule. This is a very well documented request, but a recent client wanted a slight variation – the project schedule indicator to have its tolerance based on a percentage, instead of a hard-coded value. The following formula solves this issue:
IIf([Baseline Duration]=0,"No Baseline",
Switch([Baseline Start]=ProjDateValue(‘NA’) Or [Baseline Finish]=ProjDateValue(‘NA’),"No baseline",
[Duration Variance]<=0,"On schedule",
[Duration]/[Minutes per day]>([Tolerance for schedule in percent]/100)+([Baseline Duration]/[Minutes Per Day]),"Outside tolerance",
[Duration]/[Minutes per day]<=([Tolerance for schedule in percent]/100)+([Baseline Duration]/[Minutes Per Day]),"Within tolerance"
))
This is for the task schedule RAG, and will return values based on a number field called “Tolerance for schedule in Percent” to indicate whether the task duration has increased beyond its allowed tolerance.
You will also need to set up RAG graphical indicators for this field as well, with the following values, as per the screenshot below:
No baseline = Question Mark
On schedule = Green
Within tolerance = Amber
Outside tolerance = Red
Of course, your indicators could be different to those that I have chosen, as well as the text. Just make sure to update the formula if you want to change the returned text.
Hopefully this will shorten your chin-scratching time when attempting to do something similar!

Using the “Inactivate Tasks” functionality
Inactivate task is a new feature for EPM2010; this feature enables the project manager to set certain tasks to inactive rather than deleting the tasks. This functionality is also useful for performing what-if analysis.
The following paragraph from Microsoft explains that intended usage of the inactivate task functionality:
“Microsoft Project Professional 2010 enables you to cancel a task but keep a record of the task in the project plan. This is called inactivating the task. The task remains in the project plan, but does not affect resource availability, the schedule or how other tasks are scheduled. Note: Inactivating a task is a feature available only with Project Professional.
Why would you want to inactivate a task? For one thing, it can help you model the effects of schedule or resource constraints on the project without deleting tasks permanently. Also, inactive tasks remain in the project plan, providing a record of cancelled tasks and enabling you to reactivate them if circumstances change.
Note: Inactivation is nor a good way to archive complete tasks, because it could have unanticipated effects on the remaining schedule. Instead, mark the tasks as completed.”
http://office.microsoft.com/en-us/project-help.inactivate-a-task-HA010370341.aspx
Please see the following best practise guidelines for using inactive tasks:
- When in the planning phase, if you decide that a task or tasks are not required, at this stage use the inactivate task feature to set tasks to inactive rather than deleting the tasks. this will give you the option to quickly make these tasks active at a later date if there is a requirement for these tasks.
- Inactive tasks do not affect resource availability. Baseline values that have already been taken are retained, but any new baselines taken will not include data for inactive tasks.
- Tasks that have actual work cannot be made inactive.
- Inactive tasks are not published, so inactive task assignments will not appear on a team member’s task list.
- Inactive tasks are available to report on via the Project Server OLAP cube, so care should be taken when reporting that these tasks are/aren’t included depending on the figures required. The “Task is Active” field can be used to include or exclude inactive tasks. If you do not see this field in your OLAP cube, it may be that the EPM administrator has not enabled inactive tasks in the cube.
Updating resource rates
Due to possible differences in calendars between EPM (Enterprise Calendars) and Microsoft Project (local project settings), resource rate changes using an effective from date may not be applied from the beginning of the working day. At one client in particular, where all resources in the Enterprise Resource Pool received an updated (increased) rate from the first of the financial year, this caused project financial information to be out by a couple of hundred to a few thousand pounds. Given that this particular client uses timesheet and therefore project actual work and cost figures to update their financial system for client billing, this is quite a big problem.
This article describes how to set the effective from time for the resource rate in order to ensure that it is applied from the beginning of the working day.
Setting Project Options
Open Microsoft Project and click on File > Options. Under the General tab, change the Date format to include the time, as below, and then click OK.
Updating resources
For resources that require a rate change, navigate to Resource Center in PWA. Select the resources for which the rates should be updated and click Open:
This will open the selected resources in Microsoft Project. To update the resource rate, double click on the resource and click on the Costs tab. The Effective Date will contain the time as well as the date. Ensure that the time is set to the same as the Enterprise Calendar for the start of the day.
Repeat for all resources as required. When complete, save the changes to enterprise resources (File > Save) and close Microsoft Project.
If required, change the date display setting back to show only the date by repeating the steps above.
Project Server – "An unknown error has occurred"
I recently had an issue at a client where the Project Center was failing to load and returning “An unknown error has occurred” on the page. We have seen this behaviour before and it’s usually some corrupt Project data that causes it, but I’ve never had the time to get to the bottom of the problem. Fortunately, today I had a bit more free time to investigate.
This particular issue is caused by custom fields that are linked single value (read: not multi-select) lookup tables erroneously getting multiple values assigned to them. How this occurs is as-yet unclear, but it appears to be symptomatic only in the published database – the draft and reporting databases are unaffected.
So, what’s the fix?
There are a couple of things that can be done, depending on your level of access and technical capability. Firstly, we need to identify the plans that are causing the issue. The fastest way of doing this is with a little piece of SQL code (change <Published_DB_name> to your actual Project Server published database name):
USE <Published_DB_name> SELECT (SELECT proj.PROJ_NAME FROM dbo.MSP_PROJECTS proj WHERE pcf.PROJ_UID = proj.PROJ_UID) as ProjectName ,(SELECT pcfv.[MD_PROP_NAME] FROM [dbo].[MSP_CUSTOM_FIELDS] pcfv WHERE pcfv.[MD_PROP_UID] = pcf.MD_PROP_UID) as CustomFieldName ,count(*) FROM [dbo].[MSP_PROJ_CUSTOM_FIELD_VALUES] pcf GROUP BY PROJ_UID, MD_PROP_UID HAVING COUNT(*) > 1 ORBER BY ProjectName, CustomFieldName
(credit to Jan @ Piet Remen’s blog for the above query – http://pietremen.blogspot.co.uk/2012/01/project-centre-unknown-error-has.html)
This will return a list of projects, custom fields and the number of times that the custom field has been populated. If any project appears as an output of this script, you can view view the issue by taking a look at the Project Information through PWA. Affected custom fields will appear comma separated – e.g. Project Priority: Low, Low, Low, Low – where they should only appear as a single value.
The fix is quite a simple one – republish the project. This pushes the values from the draft database back to the published database and overwrites the broken custom field values. Check in PWA > Project Information, or re-run the above query to check that the plan is now fixed in the published database. I have seen a couple of instances where this did not fix the problem, and we had to delete the published version of the plan, and re-publish from the draft version.
It is still unclear how long the project will remain “fixed”, we have had a couple of plans reproduce the issue after being republished.
Microsoft have identified the issue, and released a fix, which can be found here: http://support.microsoft.com/kb/2598251
This KB is also included in the roll-up package (http://support.microsoft.com/kb/2597152) though it’s not documented.
These KB’s will prevent the issue occurring in the future, but will not fix existing problems – be sure to follow the above steps to ensure that the plans are fixed. As always – be sure you have database backups before applying updates!
