Hi, Ollancio.
If the equipment has WBS in its master data you can use:
IE03 - to display an individual equipment or
IH10 - (as Gabriel said) to have a list of equipments and their WBS. The IH10 is good because you can personalize the layout of the list to show the WBS.
But at my actual customer, there is no WBS in the master data of the equipments. In this PM solution WBS are used only and directly in maintenance orders. In this case, if you are in a similar condition, you can use:
IW33 - to display an individual ordenr or
IW39 - to have a list or the orders and their WBS
Best regards,
