Starting yesterday, none of my Excel reports that I setup using CubeValue formulas are able to refresh. Occasionally some of the cells will return values, but most of the time all of the cells just [eventually] come back with a #N/A error. I have some Pivot Tables in the same reports using the same ODC connection and those refresh/update without any issues, it is just the CubeValue formulas that are impacted. If I edit the formula in an individual cell (i.e. start adding a new filter variable), it reads the data model without issue (suggesting fields to complete what I am typing), and most of the time after editing that individual cell will return an actual value. Same thing happens if I create a second ODC connection (to the same model) - if I repoint an individual cell to the new ODC connection, I get a value. However if I try to do a find/replace on the Worksheet with the new ODC Connection, the same issue occurs - long amount of spinning with no values being returned.
Since it's clearly not a connection issue, I'm not even sure where to start troubleshooting? I found a short thread in the Community forum referencing the same issue from a couple of other users, but no resolution. It appears to be random and intermittent based on what the other users have written.
