Adding ProDataSet before-image data in Web services
You can specify whether a SOAP Web service includes before-image data for ProDataSet parameters at all levels of the interface, including:
*At a global level for the AppObject or SubAppObject
*For each procedure or user-defined function
*For individual ProDataSet parameters of a procedure or user-defined function
By default, the Web service passes only the current data in the ProDataSet. Selecting the Write ProDataSet Before-Image in XML check box causes the OpenEdge Web service to include the before-image data for the ProDataSet parameter in the SOAP message.
