The parameter can be edited by users with modification rights in the following module:
DI001647 Project successor name
Name of the successor project
DI001201 Task successor ID
ID of the successor task
DI058213 Task successor

The parameter can be edited by users with modification rights in the following module:
DI051840 Task successor name
Name of the successor task
DI001203 Successor
DI001206 Link type
Link type
Values:
- AA: Start-Start (task A can start when task B starts)
- SF: Start-Finish (in order for task B to be finished, it is required that task A has started)
- FS: Finish-Start (task B cannot start until after task A is finished)
- EE: Finish-Finish (in order for task B to be finished, it is required that task A has finished)
The parameter can be edited by users with modification rights in the following module:
DI001216 Time interval
The time interval is the difference between the reference point for the predecessor task and the reference point for the successor task.
Details
- Both positive and negative values are permissible for a time interval.
- Positive time interval: Start of task 2 = End of task 1 + time interval.
- Negative time interval: Start of task 2 = End of task 1 - time interval. As a result, an overlap occurs.
Example
- Depending on the entry in the Link type % field, the time interval is either an absolute value (checkbox deactivated) or a percentage value (checkbox activated).
- Calculation of a percentage time interval:
- 100 x (absolute) time interval/task duration (predecessor)
The parameter can be edited by users with modification rights in the following module:
DI001489 Link total float
The
link total float of a link is the period by which the time interval of the link can be changed without exceeding the total float of the successor. It logically equates to a "total" floating time of the link. The free float of a task is the minimum free float of all successor tasks.
Note
- The corresponding field is hidden by default but can be displayed by the user if necessary.
DI001497 Link type %
Defines whether the
time interval is calculated as an absolute or a percentage value The time interval is calculated on the basis of the task duration.
Values
-
: The time interval is a percentage value which depends on the duration of the predecessor task
-
: The time interval is an absolute number
The parameter can be edited by users with modification rights in the following modules:
- Schedule (project/proposal)
- The respective data field is hidden by default and can be displayed by the user if necessary.
- Schedule (Program)
- The respective data field is hidden by default and can be displayed by the user if necessary.
DI001498 Link min.
Minimum conditions restrict the earliest times for tasks and maximum conditions restrict the latest times for tasks.
Details
- An FS link from task A to task B with a minimum condition means:
- Task B cannot start until Task A is completed.
- An FS link from task A to task B with a maximum condition means:
- the latest possible start time for task B is the time at which task A finishes.
- Combined minimum and maximum condition. If a minimum and a maximum condition of the same link type are set simultaneously between two tasks, then the tasks will be chained together. Unlike the situation in which there is only a minimum condition, in this chain there is no float between Tasks A and B, even though a requested end has been set.
Values
- - Minimum condition
- - Maximum condition

- The respective data field is hidden by default and can be displayed by the user if necessary.
- Schedule (Program)
- The respective data field is hidden by default and can be displayed by the user if necessary.
DI007348 Link calendar
The link calendar is taken into consideration in the interval calculation for subsequent dates.
The parameter can be edited by users with modification rights in the following modules:
- Schedule (project/proposal)
- The respective data field is hidden by default and can be displayed by the user if necessary.
- Schedule (Program)
- The respective data field is hidden by default and can be displayed by the user if necessary.
DI009342 Soft link
This parameter defines whether the link is to be soft or fix
Values
- = soft link
- In the case of tasks connected via soft links, the date fields are calculated as if no links existed.
- However, the successor task gets a visualization of the potential date delay (in PLANTA called "overlapping") with the predecessor.
- If a soft link is used, the dates are retained. The required shift is displayed and has to be carried out manually by changing the requested date.
- - fixed link
- If you use fixed links, dates are scheduled in accordance with the set links. Requested dates are not considered.
Example from PLANTA
project
- Fixed link with FS0
- Successor follows predecessor directly.
- Soft link with FS0
- Date of successor is determined by the set requested date.
- Red circles show the overlap with the predecessor.
