Linking to a task or resource in the MS Project file
When project plans contain hundreds of tasks or resources hyperlinks to other tasks or resources can be very useful. For example a hyperlink could you take you from a task to it's assigned resources or could link from a design task to a related prototype task. You will need the task or resource ID of the task/resource that you want to link to.
Right-click the task, resource or assignment or use Ctrl+K. Choose Hyperlink.
Type a brief description in the Text to display field.
If you don't fill in this box MS Project will default to something like "Gantt Chart!100" where "GanttChart" is the View and "100" is the task ID.
In the Link to: options select Place in This Document.
you can also link to place in the document from Existing File or Web Page by clicking the Bookmark button.
In the Enter the task or resource ID: field enter the ID of the task or resource you want to link to. You can find the task IDs by checking the grey column to the left of the task in the Task table.
Next select the View that you want to open when the hyperlink is triggered. For example you may want to link to task ID 100 in the Calendar view - Calendar!100.
If you want to link to a procurement, make sure you select a resource view like Resource Sheet or Resource Usage. Otherwise Project will create the link against a task.
Click OK to create the link.
To edit an existing Hyperlink right-click the task or resource. In the menu select Hyperlink.
