On a hardware model record, you can add substitutes to track what hardware models can
be substituted for another hardware model.

## Before you begin

Role required: model_manager

## About this task

For example, a 19" monitor can be a valid substitute for a 17" monitor. Note that
substitutions are directional so, in this case, a 17" monitor is not a substitution
for a 19" monitor. Information about valid substitute models is useful when you
select models while creating transfer orders.  
When you select substitute models, note the following conditions.

* Substitute models can be used with work management transfer orders. Substitute models are not used in procurement part sourcing.
* Hardware models included in bundled models cannot be added as substitutes.
