Some quick thoughts:
We have tried and successfully consolidated our reporting solutions to limit to Crystal and ERW. We, on 8.11 are supporting ERW mainly because of unknown changes in the horizon. For now we have a dedicated resource only for reporting needs. In Financials area, more solutions are required such as Createforms, reduced security on Crystal by our users, and hopefully Fusion can answer reporting needs.
For the folks, who are consolidation minded, we feel that reducing outsourced applications as much as possible, focusing on ERP functionalities, and retrofitting within ERP gives better throughput. Understand very difficult for management to understand, and gibbrish to the need based users.
