The LiveCompare Templates package includes a workflow template called "Survey Performance History" (in the Support Pack Analysis folder) whose purpose is to identify how much performance history data is available on a particular SAP system. It uses an RFC named SAPWL_WORKLOAD_GET_DIRECTORY to collect some of the data. Turns out that RFC is obsolete in ECC6.0 and up (at least according to this: https://www.sdn.sap.com/irj/sdn/thread?threadID=1044711&tstart=45). So it's likely that the workflow will fail on such a system.
Fortunately there is a different RFC we can use: SWNC_COLLECTOR_GET_DIRECTORY. By using that RFC and tweaking the workflow a bit I have one that runs on 700 kernel machines.
The template may be found here.
