Need Suggestion on MNI options on Other Tab in Process Model

As mentioned in placeholders of these radio buttons you don't have any process variable defined in your process model of number type or multiple value type. If you want to enable those options please add process variable of number type and with multiple values.

This is the correct answer.  To clarify, the first option will become enabled if and only if a PV of type Integer is created in the process model.  The second option will become enabled if and only if an array type PV (any PV with the "multiple" box checked) is created.  Either or both of these steps can be taken depending on what you require.

Thank you Mike to elaborate further.
