Hi!
We are using SAP BPC 7.5 MS SP 06 on SQL Server 2008 R2 on Windows Server 2008 R2 Enterprise.
Dev server (single server 12 GB RAM)
QA server (App Server - 4GB and DB Server - 12 GB)
We have P_CC dimension with 7 hierarchies and can successfully update dimension with 3834 members. But than we add more we have
encountered issue with out of memory on both servers. 
Translation from Russian (Not enough memory to complete operation. Exception fro, HRESULT: 0x8007000E (E_OUTOFMEMORY)
Is any limitation of dimension members numbers exists for BPC MS depending from number of hierarchies?
Kindly advise maybe some SQL Server settings to fix this issue.
Thanks and regards,
Iaroslav
