I'm getting the following error when trying to connect Power BI to my tabular model in AS: AnalysisServices: Cannot query internal supporting structures for column 'table'[column] because they are not processed. Please refresh or recalculate the table 'table'
It is not a calculated column and the connection seems to work fine on the local copy. I would appreciate any help with this!
This would depend on how you are processing the data within your model. If you have just done a Process Data, then the accompanying meta objects such as relationships have not yet been built.
Every column of data that you load needs to also be processed in this way regardless of whether it is a calculated column or not.
This can be achieved by running a Process Recalc on the Database or by loading your tables or table partitions with a Process Full/Process Default rather than just a Process Data, which automatically runs the Process Recalc once the data is loaded.
If you have a lot of calculated columns and tables that result in a Process Recalc taking a long time, you will need to factor this in to your refreshes and model design.
If you run a Process Recalc on your database or a Process Full/Process Default on your table now, you will no longer have those errors in Power BI.
