Hi Mithun
Thanks for the screenshots. You mentioned you do have access to Analysis Office. Can you please attach a screenshot of the same query using Analysis Office? Does it work? This will help determine if the core issue is with AOLAP or with the underlying connectivity component.
Separately, I assume this Year/Period hierarchy is a compound characteristic comprising of a Year characteristic and a Period characteristic? In the screenshots you have shown, the Year element appears to be redundant... it always shows "Y1" whereas the Period element comprises both the period and year.
To help us also determine if the issue is related to the fact that we are sorting a compound characteristic, could you just try sorting the Period characteristic instead of the compound characteristic?
Also, the screenshots you have shown above... is that the key or the text that we are seeing? If it's the key then it won't work... at least not for AOLAP... though I'd be interested to see what AOFFICE does. To get it to work for AOLAP I would expect the key to be something like 2014.001, 2014.002, 2014.003 etc.
Thanks
