It seems as if only Text is available to select. We require the Key to be available to build relationships and to view data
Note that there is a workaround involving just the Query Editor: MDX member IDs can be retrieved via an M function and a reference to the column that has the caption. Need to type Cube.AttributeMemberId([YOUR_COLUMN]) in the “Add Column -> Custom Column” dialog in the Query Editor. This will return a set of values, which are not exactly the same as the Member Key, but it should be enough to disambiguate members as the values are unique (as opposed to the Captions). This should be applied as a last step as further operations on the result set (filters, etc.) will not be pushed to the underlying BW server. Hope this helps - We're actively working on the "first class" support for selecting Key in the Navigator dialog, but hopefully this will unblock you in the interim. Thanks, M.
