RetrieveMultiple

[vital.mih]

Хочу вытащить записи по значению атрибута. Пробовал 2 разных кода:

ConditionExpression condition = new ConditionExpression();
condition.AttributeName = "new_ExtID";
condition.Operator = ConditionOperator.Equal;
condition.Values = new string[] { ExtID };

FilterExpression filter = new FilterExpression();
filter.FilterOperator = LogicalOperator.And;
filter.Conditions = new ConditionExpression[] { condition };

QueryExpression query = new QueryExpression();
query.EntityName = EntityName.account.ToString();
query.ColumnSet = new AllColumns();
query.Criteria = filter;
BusinessEntityCollection Customer = service.RetrieveMultiple(query);

и

QueryByAttribute query = new QueryByAttribute();
query.ColumnSet = new AllColumns();
query.EntityName = EntityName.account.ToString();
query.Attributes = new string[] { "new_ExtID" };
query.Values = new string[] { ExtID };
BusinessEntityCollection Customer = service.RetrieveMultiple(query);

где "new_ExtID" искомый атрибут, ExtID - входящее значение.

Запускаю через расширенную SQL процедуру, работает 7-8 минут, затем выдает ошибку: The request was aborted: The request was canceled.
