Does anybody know when support is availible for Excel 2010 in Cognos Controller ?
You are an early adopter! ;D
Excel 2010 is release somewhere in june i believe. Controller 8.5.1 is release 2 weeks later… too short to fully test this excel version.
i would say: “Next release…” 
Does you know when next release is comming ? :o
probably next year…
Controller has always been the lasted released product. First BI, planning, controller… >:(
