SQL просмотр запроса "подзапрос вернул более 1 значения"

Я использую запрос для представления, которое также используется для отчетов SSRS без каких-либо проблем в течение более 2 лет, выполняя его каждый месяц. Это запрос: 

SELECT  
    DISTINCT 
    Code= D.LocalityCode,
    [District Name]=D.LocalityName,
    Status=UPPER(D.Status),
    [Company No]=F.CompanyNumber,

    [CompanyB date]=case when F.DateCompanyB = '1900-01-01 00:00:00.000' Then NULL else F.DateCompanyB end,

Сегодня я попробовал другое время, и я получаю эту ошибку:

Сообщение 512, Уровень 16, Состояние 1, Строка 4

Подзапрос возвратил больше, чем 1 значение Это недопустимо, если подзапрос следует =,! =, <, <=,>,> = Или когда подзапрос используется в качестве выражения.

Когда я использую запрос для генерации SSRS возвращает отчет:

Я также проверил данные и ошибки при выборке 135-й строки, но это точно те же данные, что и 1 год go.

В качестве теста я удалил эти строки: 

[S Building]=(SELECT Building FROM SecAddressLookup(E.LocalityID)),
[S Street]=(SELECT Street FROM SecAddressLookup(E.LocalityID)),
[S Town]=(SELECT Town FROM SecAddressLookup(E.LocalityID)),
[S Postcode]=(SELECT Postcode FROM SecAddressLookup(E.LocalityID)),
[T Building]=(SELECT Building FROM TreAddressLookup(E.LocalityID)),
[T Street]=(SELECT Street FROM TreAddressLookup(E.LocalityID)),
[T Town]=(SELECT Town FROM TreAddressLookup(E.LocalityID)),
[T Postcode]=(SELECT Postcode FROM TreAddressLookup(E.LocalityID))

и работает только до 102 строк (даже не 134 строк) странно.

Не уверен на 100% без доступа к таблицам или UDF.
Но я догадываюсь, что адресные функции возвращают больше, чем 1 запись.

Тогда, как попытка быстрого и грязного решения, вы можете обернуть эти функции в OUTER APPLY.
с TOP 1, чтобы они возвращали только 1 запись.

Но после этого эти UDF и данные должны быть проверены на вашей стороне.
Поскольку все эти UDF не помогут с производительностью.
Возможно, эти запросы можно объединить.

вы можете использовать Top 1 в вашем подзапросе.

1) Если поле LocalityID не определено как первичный ключ в таблице tblLocality, при выполнении следующего запроса может быть указано, что виновник: 

select LocalityID, count(*) from tblLocality having count(*) >1

2) Если поле LocalityID определено как первичный ключ в таблице tblLocality это означает, что она уникальна, проблема заключается в одной из ваших функций, которые принимают в качестве параметра E.LocalityID. Поскольку у нас нет доступа к коду этих функций, мы можем видеть, какая из них вызывает и как.

Проверьте точку один и пункт два, и вы увидите проблему.
