I am looking for OLAP (BW) system response time refrences

Hi

I need to present Reference Times DIA for my BI system. I have seen the Reference Time in RFC as below in EWA report. I am not able to get any  of such values in Google for BI system. We have these reference/SAP recommended values for ECC system but was not able to get these values in BI system.

Please help me with some values that can be used as reference/SAP recommended values for BI system to mark the transactions as green-red-yellow.

Regards

Naeem
