Partitioning Table Based On A Non Primary Key Column

We are facing few issues pertaining to creation of primary key on a non - partitioned column in sql server 2005. Herewith attaching the text file containing the detailed scenario.

Pls advice.


Pls find some of the scenario with the example given below:

We have done the following steps
1.Creating a Partition Function
CREATE PARTITION FUNCTION pf_EncounterODS_StateID (CHAR(2))
AS RANGE RIGHT FOR VALUES
(
'CA', -- CA
'MI', -- MI
'NM', -- NM
'OH', -- OH
'TX', -- TX
'UT', -- UT
'WA' -- WA
)
GO
2.Creating a Partition Schema
CREATE PARTITION SCHEME [ps_EncounterODS_StateID]
AS PARTITION pf_EncounterODS_StateID TO
(
[PRIMARY],
[ENC_DM_DATA_01], -- CA
[ENC_DM_DATA_03], -- MI
[ENC_DM_DATA_04], -- NM
[ENC_DM_DATA_05], -- OH
[ENC_DM_DATA_06], -- TX
[ENC_DM_DATA_07], -- UT
[ENC_DM_DATA_02] -- WA
)
GO

3.Creating a table using above partitioned schema

CREATE TABLE [dbo].[Fact] (
[ValidationErrorSID] [bigint] NOT NULL IDENTITY(1,1),
[ProcessID] [int] NULL ,
[StateID] [char] (2) NOT NULL ,
[ClaimID] [char] (15) NULL ,

) ON [ps_EncounterODS_StateID](StateID)

4.Creating a primary key on validationErrorSID column in the fact table
ALTER TABLE [Fact] ADD CONSTRAINT NQValidationError PRIMARY KEY CLUSTERED ([ValidationErrorSID])
Step 4 throws an error as
---------------------------------
Column 'StateID' is partitioning column of the index 'NQValidationError'. Partition columns for a unique index must be a subset of the index key.
If we include StateID along with ValidationErrorSID for index,then it works fine.But we need to have only ([ValidationErrorSID]) for indexing.
