Gantt Chart

Use the Gantt Chart to view orders and resource requirement durations on a timeline along with the calculated attributes. You can also interactively modify the planned dates of a supply or resource requirement from the Gantt Chart.

You can only open the Gantt Chart in context by drilling to it from another table. Also, the Gantt chart always opens in a different pane than the pane from which you drilled from. For example, if you're using a single pane layout and open the Gantt Chart from the Supplies and Demands table, the page layout switches to a double pane (top and bottom) layout. In this situation, the Gantt chart opens in the bottom pane.

How You Drill to the Gantt Chart

You can only open the Gantt Chart in context by drilling to it from another table. Here are the tables from which you can drill to the Gantt Chart.

Drill to Context	What is Displayed in the Gantt Chart
Supplies and Demands	Supply orders
Resource Requirements	Resource requirements
Cells corresponding to these measures in the Material Plan, Build Plan, or a user-defined table: Total Supply Planned Orders Scheduled Receipts Purchase Orders Purchase Requisitions Transfer Orders Work Orders Dependent Demands	Supply orders
Cells corresponding to the Resource Requirements measure in the Resource Plan, Build Plan, or a user-defined table.	Resource requirements

Drill From the Gantt Chart to Other Tables

From the Gantt Chart, here are the tables that you can drill to and what the tables display.

Drill From	Drill to Table	What the Table Displays
Supply bar	Supplies and Demands	Supply order details
Supply bar	Material Plan	Material plan for the item-organization
Supply bar	Items	Item corresponding to the supply
Supply bar	Item Structure	Item structure corresponding to the item of supply
Supply bar	Routings	Routing of the item of the supply
Supply bar	Suppliers	Suppliers for the item corresponding to the supply
Resource Requirement bar	Resources	Resource corresponding to the resource requirement
Resource Requirement bar	Resource Availability	Resource availability of the resource
Resource Requirement bar	Resource Plan	Resource plan for the resource corresponding to the resource requirement
Resource Requirement bar	Resource Requirements	Resource requirement details

List of Order Attributes You Can Display

You can display these order attributes in the left pane of your Gantt Chart:

Order Attribute	Automatically Displayed
Item	Yes
Organization	Yes
Order Number	Yes
Order Quantity	Yes
Order Type	Yes
Supplier	No
Supplier Site	No
Source Organization	No
Ship Method	No
Work Definition	No
Item Structure	No

Supply Bar and Resource Requirements Bar

Let's discuss the characteristics of the supply bar and the resource requirement bar in your Gantt Chart.

• Supply bars span from the suggested start date to the suggested due date of the supply. If the suggested start and suggest due dates are the same, the supply bar appears as a thin line.

• Resource requirement bars span from the bucket start date of the planning time bucket that contains the start date of the resource requirements to the bucket end date of the planning time bucket that contains the end date of the resource requirement.

Show Diagnostics

You can select from the Show Diagnostics drop-down list which diagnostic attributes to display for orders and resource requirements. These are the diagnostic attributes that you can display in your Gantt Chart:

• Contributes to Demand Lateness

• Contributes to Overload

• Consumption Start Date

• Need-by Date

• Material Available Date

• Earliest Start Date

• Firm

Gantt Chart Actions

When you work in the Gantt Chart, there are some useful tool for you to use.

Action you can take from the Actions menu or the Gantt Chart toolbar	Result of the action
Move In	Moves the selected bar in by one planning time bucket. Note: You can't move a bar from a less granular time bucket, such as week, to a more granular time bucket, such as day.
Move Out	Moves the selected bar out by one planning time bucket.
Zoom In	Zooms in the time line display. You can't zoom in below the planning time bucket level.
Zoom Out	Zooms out the time line display.
Refresh	Refreshes the content in the Gantt Chart.

Moving the Bars in the Gantt Chart

Here are some pointers about moving the bars in the Gantt Chart.

• You can use the Move In and Move Out options in the toolbar or use the drag and drop action. However, you can't move a bar to another row.

• The end date of the supply bar always snaps to the last working day of the planning time bucket that you move the bar to.

• If you move a bar to a non-working day within the daily bucket portion of the plan horizon, you will be asked if you want to move it to the previous working day.

• The time durations of the bars remain the same as you move them across planning time buckets. A replan or recalculate action can change the durations.
