Component Availability Calculations
The system calculates component availability for a production order component record by calculating projected quantity on hand (PQOH) using MRP supply and demand detail information.
The system factors these key considerations when computing the time-phased consumption and supply of material:
For component demand records:
Release dates: oldest demand records processed first
Shift and sequence
Orders status: Authorized, Firmed, then Planned
R and A orders have priority over F and P orders, regardless of consumption date.
For component supply records:
Due dates
Order status: Authorized, Firmed then Planned
Expiration dates
