Consider a business scenario where I have 7 independent EBS R12 applications running in 7 regions and I need to consolidate the balances from 7 regional GL applications to FAH at PLC (Group) level in UK. These EBS applications are in different infrastructure and data can be transferred through middle layer like Biztalk. How do we achieve the design in such a situation? Can we apply co existence patch in these 7 EBS applications without Fusion being implemented there and transfer data from new co existence table through a middle layer (TIBCO or Biztalk) to Fusion tables in UK FAH tables and run Journal import in UK FAH application?
