Question
Real time example of "Page-Change-Class" method
Hi All,
I understand that "Page-Change-Class" is used to change the "pxObjClass" of the existing page assuming that the target class has all the properties referenced in the exisiting page but can anybody give me a real time example of in which situation do we use such a method? Also, how is this different from "Append and Map to" in a Data Transform? Thanks in advance.

Hi Gangababu,
Thanks for your detailed reply. I would like to know in which real time situations we would change the class of a page!
Hi Giridhar,
In situations where we wish to save our workobject to a different table we use Page-Change-Class method. Here the different table is identified through the method parameter "ObjClassNew"
To change the page context at run time, we use page-change-class method.
Please refer acquireWorkObject, createWorkPage OOB activities
Hi, While doing any Interface request and response mapping if you want to generated the structure as per your service definition Page-Change-Class is used.
Observe the classes once you import any WSDL and same is used while mapping.
Use this method to change the class of the top-level page identified in the Step Page column. (To change the class of an embedded page, see How to Change the Class of a Page.)
Before changing the class of a page, be sure that all properties referenced on the page are also defined in the target class (the destination class).
How to change the class of a page
Use the Page-Change-Class method to change the class of a top-level page.
Use the Property-Set method to change the class of an embedded page. Ordinarily, the Property-Set method requires that the source (of values) and the destination (to receive the values) be alike — assigning a string value into a string property, a page value into a page property, and so on.
However, you can establish the class of an embedded page using a special Property-Set syntax:
When the system executes this method, it sets the value of the pyObjClass property in the page to the string value. This changes the class of the page.
