Attribute key cannot be found : Data present but not processed

Question

Hi there,
I know this question has been ask several time and I went through a lot of proposed solution but none were successful in my case. My cube processed successfully for month but now I have the following error :
Errors in the OLAP storage engine: The attribute key cannot be found when processing: Table: 'EventMember', Column: 'Id', Value: '22560966'. The attribute is 'Id'.
To explain my case here what I've got.
A dimension [Member Unique] where there is a bigint Id and some attributes. The only defined attribute in the dimension is Id.
When I process fully this dimension the query issued by SSAS to SQL (using the profiler) is the following :
SELECT
DISTINCT
[dbo_Member].[Id] AS [dbo_MemberId0_0]
FROM [dbo].[Member] AS [dbo_Member]
I verified that the Id 22560966 is present in the table and in the resulting set and that is the case.
Then I have the measure group EventMember based on a named query doing the following :
SELECT Id
FROM dbo.Member AS m
WHERE EXISTS
SELECT 1 AS Expr1
FROM dbo.Event AS g INNER JOIN
dbo.MemberHistory AS h ON h.Id = g.MemberId INNER JOIN
dbo.MemberVersion AS v ON v.HistoryId = h.Id
WHERE (v.AntvoiceMemberId = m.Id)
This query returns also the row 22560966.
When I process fully the measure group EventMember the query issued by SSAS is :
SELECT [EventMember].[EventMember0_0] AS [EventMember0_0],[EventMember].[EventMemberId0_1] AS [EventMemberId0_1]
FROM
SELECT 1 AS [EventMember0_0],[Id] AS [EventMemberId0_1]
FROM
SELECT Id
FROM dbo.Member AS m
WHERE EXISTS
SELECT 1 AS Expr1
FROM dbo.Event AS g INNER JOIN
dbo.MemberHistory AS h ON h.Id = g.MemberId INNER JOIN
dbo.MemberVersion AS v ON v.HistoryId = h.Id
WHERE (v.AntvoiceMemberId = m.Id)
AS [EventMember]
AS [EventMember]
And it crashes during the process giving me the above error.
I did try to allow missing key attribute error in the process option, and it ran successfully. It allowed me to issue an MDX statement on my cube to check if the dimension member was present. And it was not the case. Hence the error I think. The MDX statement
was :
SELECT [Member Unique].[Id].&[22560966] on 0
FROM MyCube
The the final question would be : Why this member which is returned by the SQL query is not present in my dimension ?
I tried deletiong my cube it did not changed a thing. A noticeable thing is that the faulty attributes key are the same every time.

Hi RodolpheAV,
The error means SSAS could not find a record in the dimension table [table name] where column [column name] contained value [value]. For more information, you can look into the following articles:
