French character is causing duplicate attribute key errors, why and how to overcome?

hi there:
I have a retailerproductname called 'Meilleurs vœux' , this character 'œ' is causing headache as it's causing the classic duplicate attribute key errors. When I replaced it with 'e', error goes away...
The thing is that I do not want to correct datawarehouse everyday for this type of work... plus there might be other non-english characters that may pop up depends on what consumers bought.
Is there anyway other than manual intervention?
thanks

yes, try use nvarchar instead of varchar.
Using varchar Spree-Neiße <> Spree-Neisse. Using nvarchar Spree-Neiße = Spree-Neisse.
And one more specifying quiestion about your data source. Imagine you have two retailproductname, such as
Spree-Neiße and Spree-Neisse. In your case is it the same product and you should leave only one record?

Country-State-City hierarchy is driving me crazy ( duplicate attribute key errors)

hi guys:
I've a dimDesitination dimension and inside this dim , I have 4 attributes, dimDest_ID, country, state and city,
my goal is pretty simple, create a hierarchy country-state-city .
I've made sure there are no NULLs in each column, also state and city attribute, I've created composite key
for example, for state attribute , the key column is (country , state)
for city attribute, the key column is (country, state , city)
when the source dim table contains small number of data, every is fine and process full did succeed.
However, when the raw dim table gets bigger( more data comes in), the process full starts to give me error msg
says duplicate attribute key errors.... this is painful as I did check the raw table but no duplicate key found ever
any comments?
thanks

Error when build cube - A duplicate attribute key has been found when processing...

Hi all,
I got an error “Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table…” when built new cube. It looks strange in my case. I created a small example to re-produce this error as below:
I create a data source table as below
AgencyName(varchar(50))-----MediaSpend(float)
OE------------------------------------100
Œ-------------------------------------200
Then I create a cube base on this data source with a dimension AgencyName and 1 Measure MediaSpend.
The error happened again. This look link a special case when ‘OE’ and ‘Œ’ existed in a dimension.
Do you have any ideas on this?
Thanks,

Errors in the OLAP storage engine: A duplicate attribute key has been found when processing

Hi dear MSDN Community,
I am facing a problem while processing a cube with a customer hierarchy as follows:
Global Account --> Main Customer --> Master Customer --> Customer
The data comes from a flatted parent child table, that is, I create an extra column for every level of the hierarchy in the customer view. If a level is empty, then the value is filled with the previous value. Then I can use the property:
HideMemberIf = OnlyChildWithParentName for the intermediate levels (Main and Master Customer)
HideMemberIf = ParentName For the leafs (Customer)
HideMemberIf = never for the root (Global Account)
Consider this example:
Then, for the root level I am using as the key the fields in yellow in order to avoid duplicates. However, I am getting the error message "Errors in the OLAP storage engine: A duplicate attribute key has been found when processing" while processing.
I analyzed the query that SSAS issues to the server (select distinct ....) and I think it should work but it is still failing.
I had similar problems with the intermediate levels but I was able to solve it using a similar procedure.
Any help will be appreciated.
Kind Regards.

When are you having this error? While processing the dimension or during cube processing?

Duplicate attribute key found when creating a dimension

Good Afternoon,
I created a cube with dimesnions and all is working fine. I created three dimension ZONE,BLOCK and STREET and these are reltated to the FACT table and all is well. But i was thinking since these 3 dimensions are related and coming from the same table, why
not just create one dimension with ZONE as the primary key and the heirarchy as zone>block>streetname. In the DSV i created a named query.
SELECT DISTINCT ZONE, BLOCK, STREET
FROM dbo.MYTABLE
group by zone,block,street
order by zone,block,street
Please see the sample dataset as well, where when i process the DIMENSION fails with an error that the "Duplicate attribute key was found, column name:Zone, value:1). I know zone and also the other two columns when processed are repeated more than once
and hence this, is there a way to get what i want.
ZONE BLOCK STREET
1 0 Chesapeake
1 0 East Market
1 0 East Maryland
1 0 East Washington
1 0 North Capital
1 0 North Delaware
1 0 North Illinois
1 0 North Meridian
1 0 North Penn
1 0 South Delaware
1 0 South Illinois
1 0 South Meridian
1 0 South Penn
1 0 Virginia
1 0 West Georgia
1 0 West Jackson
1 0 West Market
1 0 West Maryland
1 0 West New York
1 0 West Washington
1 100 East Washington
1 100 East Market
1 100 East Maryland
1 100 East New York
1 100 East Ohio
1 100 East Washington
1 100 North Alabama
1 100 North Capitol
Thanks
SV

Thanks Richard and SS. This is what i did.
1) In the DSV i created a new named query, the same one i used.
2) Set Primary Key on Street.
3) Created a dimension STG_ZBS_DIM and while creating the heirarchy , i draged and dropped the fileds in the following order (zone>block>street).
4) Tired to process , but getting the same error, except this time at the street level.
What else i did was changed the primary key back to Zone, went into the attribute relations and set the relation from Zone to Block and then Block to Street, saved and processed and this time i got the error at the block level :-(
Thanks

A duplicate attribute key has been found when processing

Hi
When I process one of my dimensions it fails and I get the following error:
Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'Customers', Column: 'DisplayName', Value: 'Stephen Grant'. The attribute is 'Display Name'.
I don't know if this is significant, but the attribute to which it is making reference was added through BIDS 2008 (the cube was originally created with BIDS 2005).
There are no duplicates of 'Stephen Grant' in the DisplayName column. Not that it should matter if there were as this attribute has a cardinality of Many, with an rigid attribute relationship directly to the dimension's key attribute. The Key column for the Display Name attribute simply refers back to the same (DisplayName) column in the table.
If I delete this record, or even just update the DisplayName field from 'Stephen Grant' to something else, the dimension processes just fine. I can't work out what it is about this record that is stopping the dimension from being able to process.
Can anyone help me figure out what's going on?
Julia.
P.S. I am using SSAS 2008 on Windows Server 2008

Hello there,

Here i have the Hierachies in order LoanOfficerFullName-->BranchName-->RegionName. Loan Officer is the lowest level. I had created another column and make that unique entries so that I could make the unique column as the Key and the hierachies i have linked with the key column value. The issue
is that i am getting the expected result in OLAP from data side. But the data is not getting aggregated like Team Barton is coming twice though for the Dimension I make IsAggregatable property to True. If anybody can help me I will aprecciate. If any other clarification need I can provide.

Duplicate attribute key

Hi mates,
I have a postcode dimension. PostCodeKey is primary key. There are altogether 50 columns in this dimension. One column(Domestic) has NULLs which is not PK. When I process the cube, I am getting error Duplicate attribute key found.
As it is not PK, why is it reporting duplicate key?
I can add PostCodeKey in the Domestic column's key columns property. If so I need to add to all columns where I expect NULLs.
If I remove Domestic column in the dimension, cube processing is succeeded.
But, in a dimension, any column can be NULL other than the PK column.
How to fix this error?
Thanks

the are a few reasons why you may see the duplicate keys error.
For example if you have a zero and Nulls in the same column then this would be seen by SSAS as a duplicate.
It is best to treat NULLs in columns as part of your ETL.
here is a good article on duplicate keys

Duplicate attribute key in date Dimension

Hi,
I have created a date dimension using this code
http://www.codeproject.com/Articles/647950/Create-and-Populate-Date-Dimension-for-Data-Wareho
It contains one attribute 'Month'
I have created one fact table which contains the following dates
StartDate
EndDate
CreationDate
CompletionDate
AssignedDate
ReceivedDate
ActualStartDate
AcutualEndDate
DecisionDate
I have created a relationship with date dimension created by using above code. Relationship of above attributes have been created with DimDate.Date attribute. I have not created Calendar Hierarchy yet.
When I am processing the cube I am getting the following error
Errors in the OLAP storage engine: A duplicate attribute key has been found when processing: Table: 'dim_Date', Column: 'Month', Value: '10'. The attribute is 'Month'.
In date dimension have data from 1990 to 2050. so Month is being repeated for each year. I am not sure Why am I getting this error.
Any Help much appreciated.
MH

Hi Mustafah,
For the error "Errors in the OLAP storage engine: A duplicate attribute key has been found when rocessing: Table: <tablename>, Column: <columnname>. Value: <value>. The attribute is <attributename>", it can occur in multiple
situations. In many cases, the recommended solution is to change the KeyColumn by setting it to a unique attribute, or by creating a composite key that results in a unique value when multiple attributes are evaluated as a unit. Here are some document which
describe this error and the solution of it.
References:
Analysis Services: Errors in the OLAP storage engine:

[svn:fx-trunk] 21141: Bug: 2780176 - Logging and logging out multiple times in LCDS can cause duplicate session detected errors .

Revision: 21141

Log Message:
Bug: 2780176 - Logging and logging out multiple times in LCDS can cause duplicate session detected errors.
QA: Yes
Doc: No
Checkintests: Pass
Details: When a logout was followed by an immediate login, sometimes the server would throw duplicate session detected errors. This was because when logout happened, a fire-and-forget disconnect message was sent to the server that established a new session, and if the subsequent login happened before disconnect ACK returned from the server, that would establish another session and hence the error. The fix is to insert a slight delay between disconnect and ResultEvent dispatching. This way, disconnect has a chance to return before a login is performed.

You've got an incompatible Logitech driver and java was incompletely uninstalled.
You may have a problem with the Wacom driver.
I don't know if fixing those things will help.
There also a few window server errors, but I don't know if they are causal.
If you can note the time of the hangs, that might help narrow it down in the logs.

Why am I receiving the "Unfortunately, Messaging has stopped" error message and how do I fix it?

Why am I receiving the "Unfortunately, Messaging has stopped" error message and how do I fix it?

I am so upset. Please read my messages from my postings. This has nothing to do with SIM Card, Hard Reset, Apps, Google Gmail Account, nothing. I have gone thru all of this and NOTHING has fixed this. I went to the store today and spoke to the manager on duty. He said he had to try and duplicate the problem before he could help me. I showed him "screen captures" I did, told him it's out here on the board, etc. etc. Needless to say I ended up coming home with the same phone, "he" erased the phone and started over again. Well guess what, it's not a error with "MY" Gmail account being corrupted because if that is the case Mrs. Hayden14 has a bad Gmail account too. If you guessed it, the phone just crashed again! I was able this time to capture a report with ALL the history in it and saved screen captures to PROVE to him this is not a joke. Even the report says "Crash". This time it was something else I don't even or ever have used. I have also wasted over a day , yes a full work day on this without question.
I have had to get the run around for the last day. This is totally ridiculous, including them putting me on hold for 55 min. Oh, that's another funny story. Anyways, tomorrow morning I am going to the Verizon store one last and final time and I hope they decided to do the right thing and give me a phone that does not crash and works. It would be handy at work for me, especially where I work at. I hope hope hope someone listens to and helps me. I would love for them to see me walk in, take my phone and say to me were going to get you another phone, hand it to me, see if it works and prove it's the device. I don't hear anyone having this issue on other phone types so sounds like its the phone type.
I have had 3 phones now in the matter of 2 weeks. I am sure the FedEx charges will add up to a cost of a new phone at some point and start to outbalance your requirement to give me the same phone when it has the same problem.
Can't wait to see what happens tomorrow.

HT201442 hi What is error 3004 and how do I fix it?

hi What is error 3004 and how do I fix it?

Hello, Meysam321.
Thank you for the question. Here are the steps that I would recommend going through when receiving error 3004.
Resolve communication issues
Check the hosts file or TCP/IP filtering, which might cause communication issues between iTunes, ports, and servers.
Common errors: 1004, 1013, 1638, 3014, 3194, or 3000-3999. These alerts refer to gs.apple.com, say "There was a problem downloading the software", or say the "device isn't eligible for the requested build".
Resolve specific iTunes update and restore errors

Yes, unfortunatly using windows xp, this error keeps coming up. I am completely updated on Itunes, please help and thanks in advance.

I did a Google search on Error 1450, and it seems to be a 'lack of resources' issue within windows. Not related to iTunes.
Maybe shut down all other programs (including the TSR programs you may have loaded) and see if it helps?
