Cool that at least it is supported, but due to DPF restrictions not applicable for us 
As i understood in "normal" non-SAP DB2 it is possible to use BLU on partitioned DB2 so will it be in predictable future also possible in SAP BW ?
Another question - license - using BLU is available for SAP OEM DB2 customers or is it additionally licensed ?
