Entering Tasks. How Task Calendars Are Assigned, страница 2

n  When a task calendar is assigned and Ignore Resource Calendar is set to Yes, the task calendar takes precedence over the resource calendars for both working and nonworking time. In this situation resources will be scheduled for periods that are nonworking in the resource calendar if the same periods are working time in the task calendar. This scenario is illustrated in Example 3 below.

The above rules are summarized in the following table:

Table 1

Effect of Ignore Resource Calendar Option

The following table shows the effect of the Ignore Resource Calendar option when both task and resource calendars are assigned:

Scenario E represents the only situation that cannot be resolved by the general rules for task calendar scheduling. When this occurs, an error indicator is set and the following error message is displayed:

When multiple resources are assigned at once and more than one resource has a calendar that conflicts with the task calendar, the error message is displayed only once.

Examples

For Examples 1, 2 and 3, let's use a 3-day task with a task calendar assigned. The task starts on a Monday, and Saturday and Sunday are nonworking periods in all calendars.

Example 1 (Ignore Resource Calendar Set to No)

In the above example, because Tuesdays are nonworking time in the task calendar, they will also be treated as nonworking time for the resource. This is how the task would look in the Gantt Chart:
