Understanding Defining Transform Programs

This section contains information about defining transform programs

Transform Program Type

To create a transform program, in the Program Properties dialog box for the application engine program you must specify that the program type is Transform Only. After you select this option, input message name, output message name, input root element and output root element fields display.

Input and Output Message Names

When developing a transformation program, PeopleSoft Integration Broker enables you to specify the schema of the message that is going into the transform (input message and version), as well as the schema of the message that is the output of the program (output message and version).

Note:

You must specify this information when using the Oracle XSL Mapper to develop transformation programs.

These fields are required when developing transformations using the Oracle XSL Mapper.

In all other cases, these fields are optional, since there may be occasions where a transformation is general in nature and used by many messages. For example, it might be a transform that changes certain fields regardless of the message shape. In cases such as these, you would not want to define a specific input or output shape, since the transform program is only changing fields.

Input and Output Root Elements

When working with nonrowset-based messages, there may be situations where the schemas for input and output messages have multiple root elements. However, Oracle XSL Mapper uses only one of the root elements on the input side as well as only one on the output side.

When using Oracle XSL Mapper to build XSLT transformations, you may specify the input and output root elements in the Program Properties dialog box. If you do not specify an input or output root element, Oracle XSL Mapper uses the first root element in the schema.
