Edit Gantt Chart

Information

• In PLANTA project, schedules cannot only be edited in tabular view by entering the corresponding fields but also in graphical view (in the Gantt chart). The required functions can be set via customizing.

• The editing of Gantt charts is possible in the Schedule module. The following editing options are available:

  • Link (create links graphically) and delete date bars

  • Change requested date bars (requested dates) graphically.

Create and delete links graphically

Information

• Links represent dependencies between tasks.

Create Link

Procedure

• Move the cursor over the bar from which a link is to be create (source bar).

• White circles are displayed on both sides of the bar.

• Click on the circle on the side of the source bar from which the link should start. This depends on the type of the desired relationship.

• Repeat the procedure on the target bar and click on the circle at the side of the target bar to which you want the link to lead.

• The new link is created and visualized graphically as a connection line.

Note

• You can only delete links graphically in particular module variants of the Schedule module (e.g. in the base variant).

  • If you try to create a link in module variants in which graphical creation is not allowed, the following message is displayed: Cannot carry out creation.

Delete link

Delete

• In the gantt chart mark the required link row with a right-click and press DEL.

• Confirm the dialog message with Yes .

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 allowed in this area.

Change requested date graphically

Information

• When moving requested dates, you have the option to

  • move only one of the requested dates and therefore change the length of the bar

  • move both dates at once, i.e. the entire bar without changing its length

Move one of the requested dates (length of the bar changes)

• Hover the mouse over the margin of the requested start or requested end symbol.

• Once the mouse pointer becomes an arrow pointing in both directions, left-click and drag the displayed preview bar in the required direction and release the mouse button at the required position.

  • The bar length visualizing the task duration (a time period between Requested start and Requested end) will then be extended or shortened.

Move both requested dates (length of the bar remains the same)

• Mouse-over on the requested start or the requested end symbol.

• Once the mouse pointer becomes a hand, left-click on the required symbol and drag the displayed preview bar in the required direction and release the mouse-button at the required position.

  • As a result, the entire bar is moved into the required direction, and the length of the bar remains the same.

In both cases,

• a dotted line will appear, visualizing the time interval between the Requested start and Requested end (bar length) and

• a tooltip will be displayed, showing Requested start, Requested end and task duration figures between these tasks. Which parameters are displayed in the tooltip can be defined via customizing.

  • The task duration displayed in the tooltip corresponds to the bar length minus weekends and holidays.

    • The task duration can be equal to or deviate from the bar length, depending on how many weekends or holidays there are in the respective time period. This may lead to the following behavior:

      • although a date is shifted, the duration remains the same.

      • although the bar length remains the same, the duration changes.
