Processes are the smallest discrete units of work available to the Document Engine and are the level where the data is manipulated. Users can create their own Process or use one of the over 700 Processes that ship with HPE Service Manager. The Process definition consists of initial expressions, RAD, and final expressions, entered on the Initial Expressions, Initial Javascript, RAD, Final Expressions, Final Javascript, and Next Process tabs, as well as an optional call to a next Process. Expressions are written using standard RAD expressions and/or JavaScript.
