Business Process Resource Elements (Magic xpi 3.x)
An element defined as a Resource is a Source or Destination device or activity that is not a part of the process. The Resource element normally provides data input to the process or is the destination of data output from the process. You can locate a Resource element in any stage of the process.
The location of Resource elements in your business process design helps you understand the data inputs and outputs in your process, as well as the required user intervention.
