Output of one process is input for other process


Hope you can help.
I have an App. In first part, user provide orderNumber, as in_Argument for ProcessA.
Then, ProcessA starts, and give some data from out_Aurgument.
I would like to use one of out_Arguments from ProcessA, as a input argument in ProcessB.
How can I do it?
Binding value in General Properties is only for one argument.


On completion you can save the values to different app variables and then use them subsequently
