Asset Warranty in Oracle EAM

There is no automatic action/functionality included with Assets warranty in Enterprise Asset Management.
Field Warranty Status is a lookup code with no values seeded

Field Warranty Active can be set when creating work orders via EAM self service page (values
Yes/No). This field also has no validation in the application. Is just a reference field

Field Warranty Expiration Date can be set on the Asset number definition form or self service (OAF) page. It is also not affecting the system in any way. It is also just a reference field

In other words, even you see some fields which point to warranty, in fact none of these fields are affecting the application in any way. They are just reference fields in order for you to take necessary actions (manually),
So there is nothing to turn on based on current application functionality

What I could suggest to you as workaround is to create your own warranty details based on Asset attributes descriptive flexfields(DFF)

At least we can track warranty information for Assets somehow in this way but not for components (Spare parts) used for maintenance, this functionality is currently not available in EAM 
(Version R12.1)

'Asset Route' Cost Will Distribute Equally in Oracle EAM

Reason for the equal distribution of Asset route cost to its associated Asset numbers are explained at here

1. According to the new design costs no longer reside in the route asset...Instead it will get distributed to the member assets, even if you have a work order for the route asset. 
For example : 
You had a work order for the route asset, Costs for this work order will get distributed to the member assets for the route
When you look at Work Order Value Summary form, you look at costs for a particular work order...Hence in the work order value summary form, you are able to see the costs for the work order 

However in Self Service, you see Costs for an asset...According to the new design the route asset would not hold any cost.It will get distributed to its member assets.Hence route asset does not show up any cost

However if you search for costs for each of the member assets, then you will be able to track the cost of the work order, for the route asset

2. For Asset Routes.Asset route is a logical asset and costing of asset route works as below -

During the transaction processing, costs are accumulated to the A/c's in the asset route work order wip accounting class. Till the closure of asset route work order , these costs would be accounted in the WAC of route work order only.After closing the Asset route work order, these costs would then be actually distributed to each of the member asset wip accounting class variance accounts.

A Roadmap For Fusion Application

Thanks to the International Oracle User Council, we have an implementer’s view of the Fusion Roadmap. The roadmap is interactive, and each aspect of the roadmap leads to specific content for that area.
