I get this warning..
Warning 14 ....: Do not ignore duplicate key errors. Change the KeyDuplicate property of the error configuration so that it is not set to IgnoreError
seems pretty straight forward.. But I have searched the properties in BIDS 2008 for the field in question within the dimension attribute column.. And I cannot find a KeyDuplicate property anywhere.. And searching the internet brings few references to this property, and absloutely no instructions or images to help me locate it..
And the SSAS book I bought to teach me is proving very unhelpful.
