Maximo vs Oracle inventory

Our company Kangean Energy Indonesia Ltd (KEI) runs tailor made ERP for Material Management and Inventory System (MMIS) for procurement and inventory business applications by using Oracle iAS (internet Application Service) tools. It was adopted from our previous sister company for the reason of the tight time schedule for implementation. Acquiring BP Kangean doesn't mean all business application software and licenses could be transfered automatically during transition period. Alas, we had to leave all Oracle applications back to BP.
Our MMIS is now out-of-date of company requirement to have material stock status change in MMIS in terms of return material from well. Complete option for stock status changes is not supported by current MMIS.
We require multiple transactions among warehouses in the future, this feature can not be done in MMIS since in the future we will have more production sites for oil & gas (Sepanjang Island, TSB and West Kangean). We expect there will be warehouse transactions among the sites.
We are now comparing the Maximo with its inventory features and Oracle Inventory module application. Currently We run Maximo 4.1 and nearly upgrade with Maximo 6.2. On the other hand we also review Oracle Inventory application since we run iAS and Oracle database 9i. From what We have heard people on the floor, engineers maintenance people would find Maximo more aligned with processes and see as it is not Oracle as much since Oracle's strengths were in other areas (Finance, procurement). Our consideration on Oracle application is to have possibilities to have modules of business applications in package which links with each other. Besides interface between Maximo and Oracle business application is tested and matured.
Seems like we will run Maximo as Work order & asset management system and to consider Oracle application as our inventory system.
