Hi Erin
Sure, the context is a little different for you. Locations and ACM do not really conflict though. ACM is specifically concerned with conformity to the rules in the Model, not Locations. Irrespective of whether assets are ACM or not, your Location hierarchy is your best bet for saying where an asset is. Hierarchies can be designed as functional or geographical depending on your needs. Functional is where locations are part of a system - like an assembly plant might break down into functional parts of the process. Geographic represents a physical layout, like breaking your Facility into subsections as child locations, and then perhaps smaller areas within. So Fan 1 and Motor A might be in in the Location hierarchy at Facility 1 \ Section X \ Area 3. ACM won't help with this, but if you did use it, swapping assets in/out of an ACM hierarchy will then interact with the Location hierarchy when you Remove Motor A from Fan 1 to location REPAIR, and install Motor 2 from location SPARE - it will be moved from SPARE to Area 3 of Section X in Facility 1 (where Fan 1 is located).
I have seen sites where there is a one to one relationship between lowest level Locations and highest Assets, and then use an Asset hierarchy. That might be A/C Unit 1, which has Fans 1,2,3 and other children like Condenser 1 and 2 and so on. So all of A/C Unit 1's child assets are located at the same place. If these are ACM Assets, it will maintain that asset hierarchy for you also, but you can do that part without ACM.
So back to my earlier point - does ACM add any value in the context of the Facilities assets? You can still just create core-Maximo assets in the standard Assets app, and ACM won't know about those ones. But if it is ACM, installing an Asset onto a node on the parent ACM hierarchy inherits the parent's location.
