On the Ranking History tab, you can view the ranking history calculated by the system for any of the Equipment Rankings where Track History is selected. You can also manually create history records here if you have alternative ways to calculate or track ranking scores for equipment. Note that only the manually created records can be updated or deleted on this tab, unlike the records that were automatically created by the system.
Type (System Codes types entity "RATP"), Date, and Ranking Score are the only required fields on this tab. Specify Usage and a Usage UOM if the score is associated to usage of the equipment and not only age, for example the condition score at a certain mileage. Additionally, you can optionally specify End of Useful Life, Performance, and most of the other performance related attributes (see the HxGN EAM Asset Performance Management brief), linear reference data like From Point and To Point if the equipment is linear, and a set of user defined fields.
