We are having 4.7 system where HR,Finance is running.Our Client needs the functionlity of ECC 6.0 for HCM module.Currently there are interested to implement ECC where they will be using only HR module & the finace will be there in the existing 4.7 system.Will it be possible to use SAP HCM in ECC with Finance in 4.7 system??If it works how to do that?Is it through SAP PI?
The best solution would have been to upgrade the 4.7 system to ECC6 and to use Finance and HCM in the same system.
R/3 4.7 will soon be obsolete... So the ECC6 upgrade will anyway be needed soon.
If you absolutely need 2 systems , yes you can connect ECC6 HCM to R/3 4.7 through ALE/idocs. It is especially needed if you will do the payroll on the HCM system.
Oliver my client now proposing for Technical upgrade from 4.7 to ECC 6.0...
But they will be using Finance in 4.7 still & use ECC 6.0 only for HR/Payroll..
Can the Data Cleansing (removal of Finance data copied from source 4.7 system as part of upgrade) be possible??
Integration between SAP ECC6 & 4.7 systems will be done via PI.
