Description

Projection schedules are core pre-requisites to almost all projection calculations.  They are generated once per flock/house, and their results are reused throughout the projection report in for every period in various calculations.   Projection schedules are composed of projection days.  Each day has a value which is either generated from actual transactions, from standard projections, or from a combination of the two.   This document describes the logic for projection day calculations integrated into the projection report.  In addition, it describes the generic algorithm for the projection configuraiton adjustment, also known as standard adjustment value (SAV).   The SAV is applied to all projection schedules to 'even out' the transition from actual to projected values.
