Union query filtering duplicated records

[Guest]

What do I need to change so this query will not filter out duplicate records?
I know there is an ALL function but I cannot get the syntax to work.

TRANSFORM Sum([UNION - Gas Revenue and Other Customer Revenue].[Current
Value]) AS [SumOfCurrent Value]
SELECT [UNION - Gas Revenue and Other Customer Revenue].[District Code],
[UNION - Gas Revenue and Other Customer Revenue].Source, [UNION - Gas Revenue
and Other Customer Revenue].[District Name], [UNION - Gas Revenue and Other
Customer Revenue].[Report Date]
FROM [UNION - Gas Revenue and Other Customer Revenue]
GROUP BY [UNION - Gas Revenue and Other Customer Revenue].[District Code],
[UNION - Gas Revenue and Other Customer Revenue].Source, [UNION - Gas Revenue
and Other Customer Revenue].[District Name], [UNION - Gas Revenue and Other
Customer Revenue].[Report Date]
PIVOT [UNION - Gas Revenue and Other Customer Revenue].Category;

I am guessing that you don't need to change this query. You need to change
the UNION query it is built on. In the source query change UNION between
the query clauses to UNION ALL
