Prerequisites before J2IUN

Hello all,

I have gone through some threads, but still not getting clarity :-(

1.Kindly explain the prerequisite steps to run J2IUN.

I mean, once MM transactions (eg:j1iex) and Sales transactions (eg:J1IIN) completed, then can we go for utilization..?

Does system take automatically from all types of scenarios transactions input and output..? if not what transactions we need to perform.?

Thank you
