Order Component Specification Editor Duration Tab

Use the Duration tab to define the processing durations for each order component. OSM uses either the order component specification duration or the orchestration fulfillment pattern order component duration, whichever is longer, to calculate the start date for order components. See "Orchestration Fulfillment Pattern Editor Order Components Subtab" for more information.

If Use Calculated Start Date is enabled, the order component will not start until the calculated start date is reached. If the current date and time are greater than calculated start date, then the calculated start date is ignored.

If Use Calculated Start Date is disabled, the order component starts as soon as all preceding dependencies are resolved.

The calculated start dates are only used if there is sufficient time to meet the date. Otherwise, the order component begins immediately.

See "Order Component Specification Editor Details Tab" for more information about Use Calculated Start Date.

OSM uses several configured durations to calculate the start times for order components. See OSM Modeling Guide for more information.

Field	Use
Optimistic Processing Duration area	Specify the minimum amount of time OSM can expect to process a single order item for the associated order component. Do one of the following: Define a specific duration in the Duration fields. In the Duration Expression field, enter an XQuery expression or a pointer to a file or URI to determine the processing duration based on a specific order item property. See "About Creating XQuery Expressions with Design Studio" for more information about entering information into XQuery controls. See "About Component Specification Duration XQuery Expressions" for more information.
Most Likely Processing Duration area	Specify the most likely amount of time OSM can expect to process a single order item for the associated order component. Do one of the following: Define a specific duration in the Duration fields. In the Duration Expression field, enter an XQuery expression or a pointer to a file or URI to determine the processing duration based on a specific order item property. See "About Creating XQuery Expressions with Design Studio" for more information about entering information into XQuery controls. See "About Component Specification Duration XQuery Expressions" for more information.
Pessimistic Processing Duration area	Specify the maximum amount of time OSM can expect to process a single order item for the associated order component. Do one of the following: Define a specific duration in the Duration fields. In the Duration Expression field, enter an XQuery expression or a pointer to a file or URI to determine the processing duration based on a specific order item property. See "About Creating XQuery Expressions with Design Studio" for more information about entering information into XQuery controls.
