Hi Falua, yes it is possible. Assuming you are calling Process 2 from Process 1 - On the Start stage of Process 2 configure the Input parameters (as many as you want). Then in Process 1 when you call the Process 2 using a Process stage, it will automatically ask you to provide the values to those parameters in the Inputs tab. Here you will pass the data items that is generated/calculated in Process 1 (meaning output of Process 1).
