You are implementing BPC 10.1 Embedded Model and would like to know the official SAP recommendation for the Office front-ends / client.
In SAP Note 2312162, we have clearly recommended Analysis for Office (AO) plug-in. This recommendation is based primarily on some architectural advantages of the AO plug-in on SAP BW meta model – compared to the EPM plug-in.
However, you can still use EPM plug-in/add-in on BPC Embedded Model if you are aware of these architectural (functional and performance) limitations listed in that note.
Please note that with the next support packages of EPM Add-in (EPM 10 SP27, RTC planned in September) and Analysis Office (2.3 SP 2, RTC planned in September), the access to an BPC 10.1 Embedded Model is deactivated by default.
If you are already using or if you plan to use the EPM Add-in/plug-in on top a BPC 10.1 Embedded model, please follow the process described in SAP Note 2327742.
