What this term means in maintenance
A material reservation allocates available spare parts or materials to a specific maintenance job so they are not consumed by unrelated work.
Why materials are reserved
Reservation improves confidence that planned work can proceed when scheduled.
A reservation may include:
- Work order
- Part
- Required quantity
- Reserved quantity
- Store location
- Required date
- Reservation status
Practical example
A seal kit and two bearings are reserved for a planned pump overhaul next week.
Reservation versus issue
Reservation earmarks stock.
Issue records that the material has physically left inventory for the job.
Availability
The system should distinguish on-hand, available, reserved, ordered, and backordered quantities.
Common mistake
Reserving material indefinitely for postponed work can create artificial stock shortages.
How this term differs
Material Reservation is the allocation of stock to a planned job without physical issue. It is related to Parts Issue, Parts Return, and Goods Receipt, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
