About Order Priority XQuery Expressions

This topic describes how to use the Order Recognition Rule editor Order Priority area XQuery tab to write an expression that specifies an element value in the incoming customer order that identifies the order priority. The XQuery has the following characteristics:

  • Context: The input document for the Order Priority XQuery is the customer order. For more information about typical customer order structures, see OSM Modeling Guide.

  • Prolog: You can declare the customer order namespace in the XQuery prolog. For example:

    declare namespace im="http://xmlns.oracle.com/InputMessage";

  • Body: The Order Priority body must specify the node that contains the order priority value.

For more information about creating order priority XQuery expressions in the order recognition rule and about creating order priority ranges for an order type, see OSM Modeling Guide.
