It now appears that no matter what combination of appending queries I try , I get the following error ....
Formula.Firewall: Query 'Bid_Vol_History' (step 'Appended Query1') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.
According the the query dependency view , the sub queries being appended into the final query are correctly linked to their respective (csv file) data source.

Hi pat_energetics,
If you did any operation in Query statement? How about you reload the data?

Tried that several times with reload / restructure queries / reorder queries - all without success unfortunately....
