Thanks for your reply Vijay_A_Verma but unfortunately it didn't work.

 

It gives me a new (similar) error:


Formula.Firewall: Query 'Query1' (step 'Changed Type') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

Create a a new blank query and paste the following code inside it (Rename the query to StagingQuery). You will probably don't need to load the data in report, hence right click on this query and uncheck Enable load

 

let
    Source = Sql.Database("tcp:axbyod.database.windows.net,1111", "ax_dev_demo",
    [Query="exec [dbo].[getSelectedAccounts] '"& accounts &"','"& startDate &"','"& endDate &"','"& queryParam &"','"& voucher &"','"& program &"','"& programType &"','"& project &"','"& province &"','"& department &"','"& university &"'"])
in
    Source

 

Now, in the original query, delete everything and paste following and check whether the message disappears

 

let
    Source = StagingQuery,
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Contract Year", type date}, {"Date", type date}, {"Document Date", type date}})
in
    #"Changed Type"
