Overview

Parameters held in under the maint_pred lookup set key comprise constants that are used in the assignment of Routine Maintenance.

Lookup Set Key

The key to identify this set in the model code is ‘maint_pred’ (case-sensitive)

Change Level

Parameters held under the maint_pred lookup set should be reviewed for each project type.
