[#2 · Accepted solution]

Please check in your MainData table whether there is a field called 'Period'. That is the main error. Once you fix that, other errors will disappear.

Actually, there is a aliased field Period in MainDataTable as shown below. It looks like the book might have an error -

     Period

  & ' | ' & [%Airline ID]

  & ' | ' & [%Unique Carrier Code]

  & ' | ' & [%Carrier Group ID] as [%Key Field],

[#4]

can you post the statement for MainData, You are missing a comma after the work 'Period'. Please double check.

My mistake. The book told me to -

Create a new compound key on both of the tables by using the following

script expression:

Period

& ' | ' & [%Airline ID]

& ' | ' & [%Unique Carrier Code]

& ' | ' & [%Carrier Group ID] as [%Key Field],

I replaced Period by the above code.

Thanks.
