• When SSAS errors you will often see the error messages under the measure group or dimension (whatever has failed) that are processing at the time whether they have failed or not.

    Expand all the measure groups/dimensions and look at each error message. Some of the error messages will be a generic error message as the processing has been cancelled by whatever has errored. Eventually you will find the correct error message

    Clear? It is a bit of a mission and I often get my support team misinforming me due to this
