'Invalid column name' error (code 260) for every join
I've created a data set in my trial space on the Warehouse Cloud using CSV uploads which consists of 5 tables out of which one is a transaction data table, one master data, 2 text tables and one mapping table to link master and transaction data.
The idea was to create an attribute view by joining the master data and text tables, a second view by joining the transaction and mapping data tables and then bring all these views together in an analytical view.
However I'm having trouble getting even a single join to work. Every single join throws an 'Invalid column name (code 260)' error even though there are no such errors in the underlying tables. There is no information on how to resolve these errors. Any advice on how to proceed would be very welcome.
