title: why do we use tibco mapper activity?
body: <p>The tibco documentation says</p>
  
  <p><em>The Mapper activity adds a new process variable to the process definition. This variable can be a simple datatype, a TIBCO ActiveEnterprise schema, an XML schema, or a complex structure.</em></p>
  
  <p>so my question is tibco mapper does only this simple function.We can create process variables in process definition also(by right clicking on process definition).I looked for it in google but no body clearly explains why to use this activity and I have also tried in youtube and there also only one video and it does not explain clearly.I am looking for an example how it is used in large organizations and a real time example.Thanks in advance</p>
