Integrating R12 HCM with 11i Finance and OPM
We are trying to evaluate the options surrounding the upgrade to R12.1 from 11.5.10.2. Because of the huge level of customizations we currently have in OPM and Finance modules in 11i and considering the cost involved in moving, testing and fixing them again in R12, we do not want to go to R12 yet. But since HCM, particularly Payroll module, needs to be up to date with the latest statutory patches, we cannot hold back from moving to R12.
Hence, we are mulling over an idea of moving HCM to an R12 instance while maintaining the other modules (OPM, Finance) in the existing 11i instance. I believe we need to develop interfaces b/w the R12 HCM and the 11i Finance/OPM modules to maintain the data in sync (like the Transfer to GL, Employee/assignment, Location details etc)
