What are Reservation Type in Maximo?

In Maximo 7.5, planned material line on a work order allows the users to specify various inventory item reservations types: AUTOMATIC, HARD, SOFT

HARD Reservation is a time sensitive reservation. Hard reservation is based on a first in, first assigned basis. If a hard reservation comes in, the inventory then modified accordingly.

A soft reservation only ensures that items or tools are being reserved for the work order and this reservation type is not time sensitive.

Automatic processing type considers the required date specified on the work order
