A process definition contains three Call Process activities. Each process has the same input schema and needs the same input data. What is the most efficient way to pass data from the main process to the three subprocesses?
using XPATH custom functions when configuring the mapping
using a Job Shared Variable to store the input data needed by the three subprocesses
replacing the default XSLT code with an optimized one when configuring the mappings
having a Mapper activity with output mapped to the input needed by the three subprocesses
