An NJE transfer unit is a unit of work that is transmitted across the network. An NJE transfer unit can be either an NJE job or a nodal message record (NMR).

An NJE job is a transfer unit that contains data to be processed at another node in the NJE network. It begins with a job header, is followed by data, and ends with a job trailer. The type of data contained in the NJE job further defines the type of NJE job. The data between the job header and job trailer can be either SYSIN or SYSOUT data. An NJE SYSIN job is an NJE job that contains JCL for a job and may have one or more SYSIN data sets. An NJE SYSOUT job is an NJE job that contains one or more SYSOUT data sets. Each SYSOUT data set is preceded by a data set header.

A nodal message record (NMR) is a unit of work that begins with an NMR header and is followed by message text. The message text can be either a message or a system command.
