On this tab you can see all equipment and all templates where the header RCM template has been imported in the past. Remember the user is free to change the imported data on equipment or on templates after the import is completed. This includes removing the imported data. Therefore, it may be possible that this tab shows equipment and templates where all imported data has already been removed.
If the selected template has Failure Mode Library selected, this tab also shows equipment and templates with a failure mode that references this failure mode library template. These failure mode records have the Failure Mode Library checkbox selected in the grid and they show the Failure Mode Description as well on this tab. Both these fields will be blank if the template was imported.
Note that since you can import failure mode library templates, it is possible that you will see two records referencing the same equipment. One because of the import, and one that references the imported failure mode.
