About Order Item Dependency Property Correlation XQuery Expressions

This topic describes how to use one of the following fields:

Fulfillment Pattern editor, Orchestration Plan tab, Dependencies tab, Order Item Dependency subtab, XQuery subtab for the Property Correlation selection
Orchestration Dependency editor, Order Item Dependencies tab, XQuery subtab for the Property Correlation selection

to write an expression that specifies dependencies between different order items using order item properties. The Property Correlation XQuery has the same context, prolog, and body structure as the Fulfillment Pattern editor, Order Components tab, Order Item Association subtab, XQuery subtab. See "About Associating Order Items Using Property Correlations XQuery Expressions" for more information.

The following example shows a dependency that requires provisioning of an Internet service before shipping a modem. This involves two order items: provision Internet service and ship modem. The correlating property is the order item ID.

declare namespace osm="http://xmlns.oracle.com/communications/ordermanagement/model";
declare namespace im="http://sample.broadband";
let $bbProvision := osm:fromOrderComponent/osm:orderItem[osm:name="Internet Service"]
let $bbModem := osm:toOrderComponent/osm:orderItem[osm:name/text()='Broadband Modem' 
   and osm:properties/im:SiteID/text() = $bbProvision/osm:properties/im:SiteID/text()]
return
   <osm:dependency fromOrderItemId='{$bbProvision/@id}' toOrderItemId='{$bbModem/@id}'/>

In this example:

$bbProvision contains the broadband service order item in the blocking Provision order component.
$bbModem is the broadband modem in the waiting Ship order component.
The XQuery returns a dependency from the Internet Service order item to its associated Broadband Modem order item, identified by $bbProvision/@id and $bbModem/@id.

If the order item IDs are:

$bbProvision/@id = 1301589468772
$bbModem/@id = 1301589468785

Then the XQuery returns the following:

<osm:dependency fromOrderItemId='1301589468772' toOrderItemId='1301589468785'/>
