We are sorry but there's no way to hide the links on the Gantt Chart without removing the predecessors/successors from the tasks.

To unlink two tasks, please delete or uncheck the Task ID from Predecessors/Successors column, or select both tasks and go to menu Task - Unlink. To change the Start date for a task, please make sure that the % complete is set to 0.

FS is an abbreviation for Finish to Start dependency. It forces a task to start only when/after its predecessor/successor has finished; predecessor/successor finishes and the other starts.

To add Successor to tasks, go to Gantt Chart view and in Successors field insert the Task IDs or select the successors from the field's drop-down list.

To add a start to finish dependency between tasks, you need to establish a Start to Finish dependency in the Predecessors or Successors column or in Task Information dialog under the Predecessors tab.

To make a Start-to-Start relationship between tasks, you need to establish a Start to Start dependency in the Predecessors or Successors column or in Task Information dialog under the Predecessors tab. For example, you have task ID 1 and task ID 2 and you want to establish a Start-to-Start dependency. In task ID 2 on Predecessors columns write 1SS.

There are two ways to establish a relationship between two tasks or link two tasks:

1. Click on the task that will be dependent and go to Task Information – Predecessors – select the task that will dictate the relationship and the type of link between them – click OK.
2. Enter the ID of the task in the Predecessors/Successors field. You can enter the ID of the predecessor/successor and this automatically creates a Finish-Start link from the predecessor/successor to the current task or you can enter the ID of the predecessor/successor followed by the link type - a value in {SS, SF, FF}.

The Start to Finish dependency forces a task to finish only when/after its predecessor/successor start. If a nonzero lag is present, it is added to the Finish date.

The Start to Start dependency forces a task to begin only at the same moment with its predecessor/successor or after its predecessor/successor started; the start of the predecessor/successor determines when the other starts. If a nonzero lag is present, it is added to the Start date.

The Finish to Finish dependency forces a task to finish only when/after its predecessor/successor is completed; both tasks finish at the same time. If a nonzero lag is present, it is added to the Finish date.For instance, a value of 4FF+2 days in the Predecessors column signifies a Finish - Finish type link with a lag of two days, where the current task has the task with ID = 4 as its predecessor.

The Finish to Start dependency is the default link type applied. It forces a task to start only when/after its predecessor/successor has finished; predecessor/successor finishes and the other starts.A link can also have a "lag" value specified. Finish-to-start is the most common dependency type. If a nonzero lag is present, it is added to the Start date; otherwise, the task starts immediately after the predecessor/successor is completed. A positive lag value will create a gap between the finish of one task and the start of another.
