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.
