Working with fixed task sets
In some cases, you may want a user of a project to be able to move around the project hierarchy and move charts (expanded tasks) around the hierarchy, from one place to another, without letting them change the objects inside the chart.
You can do this by editing the access rights of the security group to which a user belongs and denying the members of the security group deletion and modification rights for a chart, but enabling them to move the chart. The chart then becomes a fixed task set, that is a chart or subchart that a user is able to move around the project hierarchy, but is not able to edit. As access rights are hierarchical, if you make one chart a fixed task set, its subcharts become fixed task sets too, unless you specify different access rights for them individually.
As access rights are defined individually for each security group, a chart can be a fixed task set for the members of one security group, but a normal, editable chart for the members of another security group.

- Right-click the security group in Library Explorer and select the Properties. The Security Group Properties dialog appears.
- Click the Chart Access Rights tab. This tab displays the chart hierarchy. The hierarchy of expanded tasks and summary tasks is displayed under the chart that represents the programme.
- Select the chart that you want to make into a fixed task set for members of the security group.
- Use the check boxes to grant and deny members of the security group access rights for the bar chart objects within the selected chart as appropriate. For example, you may want them to be able to view items within the chart, but not create, delete or modify them.
- Select the Move Chart check box. This turns a chart into a fixed task set.
- OK the dialog to confirm the access rights you have specified.
Members of the security group can now move the chart around the project hierarchy, but cannot edit the chart. Note that in order to move one chart into another chart, members of the security group must have Create rights within the other chart.

If you have defined a chart as a fixed task set for the members of a security group, they are able to move around the hierarchy of a project, and move the fixed task set around within the hierarchy, but are unable to edit the contents of the fixed task set.
As access rights are hierarchical, if you make one chart a fixed task set for the members of a security group, its subcharts become fixed task sets too, unless you specify different access rights for them individually. This means that members of the security group can move the subcharts around in the hierarchy, but cannot edit their contents.
Defining a chart as a fixed task set for the members of a security group does not affect the way in which the members of other security groups can use the chart.
