Links

Information

• Links represent dependencies between tasks of a project and have an impact on the calculation of the project dates.
• For a description of further options for mapping dependencies, please click here. 

Create Link

Links can be created both in table form or graphically

In table form

• To do so, right-click on the required task in the Schedule module or right-click in the Task module and select the Insert → Links context menu command.
  • Fill the following fields in the new link record:
    • Task successor
    • Link type (here, the Link type = "FS" is preset by default).
    • Time interval (if required).
  • Save.
  • Then click on the

    

    Calculate schedule button in the toolbar of the Schedule module to recalculate the schedule.

Graphically in the Schedule module

• Move the mouse pointer to the bar from which a link is to be created (source bar). Instead of the mouse pointer, a cross will be displayed.
• Place the cross at the beginning or at the end of the source bar depending on which link type you wish to create (e.g. for the Finish-Start relationship, place the cross at the end of the source bar).
• Click and hold the left mouse button and drag the mouse to the beginning or to the end of the target bar depending on what link type you wish to create (e.g. for a Finish-Start relationship drag the mouse to the start of the target bar). As a result, a connection line between the two bars will be displayed.
• As soon as the destination bar is reached, the start position in the source bar and the destination position in the destination bar are marked by yellow arrows.
• Release the left mouse button. The new link will be created and will be visualized as a connection line.

Graphical editing of links in the Task module is not possible.

Cross-Area Links

Information

• It is possible to create cross-area links graphically between gate bars and task bars

Procedure

• In order to be able to create links between gates and tasks in the Gantt chart, the Schedule with Gates parameter must be activated in the required project (in the Project Core Data module).
• The creation procedure is the same as for regular tasks: Drag the link from the required task bar in the Gantt chart to the required gate (please make sure that you do not release the link on the name in the gate but on the margin).
  
  • As a result, a double link is created: to the required gate below the scale and to the respective master milestone in the Gantt chart. If a link is dragged to a master milestone in the Gantt chart, a double link to the respective gate is created. If such a link is edited afterwards (e.g. if the type is changed or deleted), both links are always changed accordingly.
    • Reason: Since gates are physically/logically identical to master milestones in the Gantt chart, two links are implicitly created when they are dragged.
• Links can only be created from task bars to gates but not the other way around (from gates to task bars).

Notes

• Links between parent (summary tasks) and child tasks which possibly exist in structured schedules are not considered in the calculation of the schedule, so that no network cycle occurs.
• If the No links on master milestones parameter is activated, no links can be created to tasks that are defined as master milestones. This is indicated by a message.

Edit Link

Information

• Every link can be edited in the respective fields of the table view by changing the required link parameters. The most important parameters are:
  • Link type ( this parameter can also be changed in graphical view by right-clicking on the required link line)
  • Time Interval
  • Soft link

Delete link

In table form

• Mark the required link line.
• Click on the delete symbol in the toolbar.

Graphically

• Click on the required link line in the Gantt chart to have it highlighted.
• Then right-click and select the Delete link context menu command.

Note

• You can only delete links graphically in particular module variants of the Schedule module (e.g. the Base variant).
  • If you try to delete a link in module variants in which graphical deletion is not allowed, the following message is displayed: Deletion not permitted in this area.
