Message Part Structures

Message parts are rowset-based messages or nonrowset-based messages that you designate as a part message on the message definition. Message parts are used in container messages

Message parts can be re-used in multiple containers.

All parts in a container must be of the same type (Rowset-based or Nonrowset-based).

You create messages using the Message Builder page in the PeopleSoft Pure Internet Architecture.

Rowset-based message parts provide all the ease of use of using rowsets, yet the generated XML message is industry standard and not PeopleSoft proprietary. Rowset-based message parts, like nonrowset-based parts, can only be part of a container type message.

These are the benefits of using Rowset-based parts:

• The XML schema generated is standard XML and not the PeopleSoft message format. Rowset-based message parts do not have a PSCAMA section, FieldTypes section, IsChanged attributes, and so forth.

• The message API for rowset-based parts is simple to use and understand.

• XML serialization and deserialization to and from part rowset is provided by Integration Broker framework.

• You can use a CopyRowSet type method to populate the rowset from another rowset (component rowset).

The following example shows a sample schema from a rowset-based message part:

A nonrowset-based message part schema is similar to a regular nonrowset-based message, however a nonrowset-based message part can be reused in multiple containers.
