Manually calculate Time Period conflicts for a change

User Roles: Change Manager; Change Coordinator

Note This feature applies only when Service Manager Calendar and the Time Period Management functionality are used. It does not apply to Release Control time periods if Release Control is used.

When planning a change in the out-of-box system, if you enter a Scheduled Implementation Start and a Scheduled Implementation End value and then the change record is saved, HPE Service Manager automatically calculates possible conflicts of the time range you enter with existing Time Period freeze and maintenance windows. If Service Manager has detected any conflicts, it displays a warning and turns on the Time Period Conflict flag in the change record.

Note By default, the Disable the Pop-up Window to warn time period conflicts option is not selected in the Time Period global settings, which means Time Period conflict warning messages are displayed in a pop-up window by default; when this option is selected, such warnings are displayed only in the message history box.

Automatic Time Period conflict calculation

Time Period conflict calculation is defined in the Calendar Mapping record for the Change object. To view this record, follow these steps:

Navigate to System Administration > Ongoing Maintenance > Calendar Administration > Calendar Mappings.
In the Object field, select Change.
Click Search. The Calendar Mapping record for Change opens.
Scroll down to the Time Period Mapping section, and view the following settings:
- Field for Start Date
- Field for End Date
- Time Period Mapping Query
- Query for Time Period Conflict Calculation
For a description of each setting, see Display records from an application module in the calendar.

Manual Time Period conflict calculation

Automatic time period conflict calculation is triggered only when changes are saved to the fields in a change record that are mapped to Field for Start Date and Field for End Date in the Time Period Mapping for Change. There are times when Time Period conflicts need to be manually calculated. For example, when there are updates made to Time Period records or to the Time Period Mapping definition for the Change object, or when you have changed the Category of a change record while the Category field is being referenced in the Query for Time Period Conflict Calculation expression, you need to manually trigger Time Period conflict calculation.

To manually calculate Time Period conflicts for a change record, follow these steps:

Click Change Management > Search Changes in the System Navigator.
Locate the change record you want to view.
Click More or the More Actions menu, and select Calculate Time Period Conflicts.

Note This option is available only for a change that is not closed and is eligible for Time Period conflict calculation based on the settings in the Calendar Mapping for the Change object.

Service Manager recalculates Time Period conflicts for the change record and performs the following actions:
- Displays the following message when the recalculation is complete: Recalculation of time period conflicts complete.
- Clears or turns on the Time Period Conflict flag in the change record according to the recalculation result.
