Measure object in WebI shows #DATATYPE

Hi,

One of the RKF's that I am using in WebI shows #DATATYPE. All the other RKF's are working fine. Our Universe is based on BEx Query. We did not make any changes after we built the OLAP Universe. I refreshed the Universe couple of times, still there's no change. I checked the SELECT statement of this measure, which looks fine and parsing is also OK.

Is there any setting in BEx that I am missing or is it something to do in the Universe.

Please help me on this issue

Thanks,

Krishna
