16.When two or more concurrent tasks depend on a single prior task, each of the concurrent tasks is calleda predecessor task.PTS:1REF:99
To remove a link, select the two linked tasks and then choose Task > Unlink Tasks .Project creates a simple finish-to-start task link by default, which means the first task (the predecessor) needs to finish before the second task (the successor) can start. If you are a Project Online subscriber, you can also select specific tasks to link to using a drop-down box from the Predecessors or Successors column.
Selecting links from the drop-down is especially useful if the task you want to link to is not located close to the task you're linking from. You can set up Project so that when you insert a new task between linked tasks, the new task is automatically linked to the surrounding tasks.
When you link a manually scheduled task to another task, Project places the manually scheduled task relative to the other task. You can configure Project so that a manually scheduled task does not move when you link it to another task:

Top of Page After tasks are linked to create task dependencies, you can easily change or remove the dependencies, if needed, by doing any of the following: Change the link type of a task dependency By default, Project links tasks in a finish-to-start dependency. You can, however, easily change the type of task dependency on the Advanced tab of the Task Information dialog box. To open the Task Information dialog box, double-click the name of the task whose link type you want to change.
Note: Double-clicking a link to an external task opens the project containing the task, if the project is available. Externally linked tasks appear dimmed in the task list. If you want to modify the link type for an external task, double-click the externally linked task to open the project that contains the task, and then do the following to modify the linked task. For example, if you linked Task A in Project Z to Task 1 in Project 5, you can modify the link type in the task information for Task 1.
Link to a different task If you have a task that is currently linked to the wrong task, you can easily modify the link so that it reflects the correct dependency.
Remove all dependencies for a task If your task is no longer dependent on any other tasks, you can remove all of the task's dependencies at once.
Note: Removing a task link removes the dependency between two tasks, as indicated by the link lines between the tasks. If you want to change the hierarchical structure of a task or subtask as part of an outline structure for your project, then you need to outdent the task rather than remove the task link. Remove specific task dependencies If your task is linked to several tasks and you need to remove specific links while leaving some intact, you can choose which links to remove in the Task Information dialog box.
You can configure Project so that when you insert a task among linked tasks, the new task is automatically linked to the surrounding tasks. This is called autolinking. For example, if you have three tasks with finish-to-start links and you add a new task between them, the new task will take on a finish-to-start link with the tasks above and below it. By default, autolinking is disabled. Follow these steps to turn autolinking on.
When you link tasks in Project, the default link type is finish-to-start. However, a finish-to-start link does not work in every situation. Project provides the following additional types of task links so that you can model your project realistically:
If you linked your tasks but the successor task doesn't move, there may be several causes:
Here are some possible resolutions:
These instructions are specific to Microsoft Project 2007. When you link tasks in Project, the default link type is finish-to-start. However, a finish-to-start link does not work in every situation. Project provides additional types of task links so you can model your project realistically.
When inserting a task among linked tasks, you can have a new task linked automatically or not link it at all.
By default, when you insert a task among linked tasks, the new task is automatically linked with the surrounding tasks. For example, if you have three tasks with finish-to-start links and you add a new task between them, the new task will take on a finish-to-start link with the tasks above and below it. You can easily turn this option off, so that inserting a new task does not automatically link it with the surrounding tasks. If autolinking is turned off, you can easily turn it back on.
