Invalid column name 'SKEY_VAL' Error when Populating a planning dimension

Question

I'm trying to populate a planning dimension from a view in MSSQL. I thought that I had mapped the all of the required columns in my interface in ODI, but I am getting the following error:
207 : S0001 : com.microsoft.sqlserver.jdbc.SQLServerException: Invalid column name 'SKEY_VAL'.
I can see in Operator that ODI is generating the following SQL
select     
     LEFT(DIM_ACCOUNT.FLEX_VALUE,80)     as C1_ACCOUNT,
     DIM_ACCOUNT.PARENT_FLEX_VALUE     as C2_PARENT,
     LEFT(DIM_ACCOUNT.DESCRIPTION,80)     as C3_DESCRIPTION,
     LEFT(DIM_ACCOUNT.DESCRIPTION,80)     as C4_ALIAS__DEFAULT,
     SKEY_VAL
from     DOT_STAGE.dbo.DIM_ACCOUNT_T_V as DIM_ACCOUNT
where     (1=1)
But I don't know why it is asking for the SKEY_VAL column or how I can map a value into this column when setting up the interface?
I've read through the user guide and the getting started guide and I can't find any reference to this SKEY_VAL column.
Does anyone know what causes this error and how I can fix it?

Answer 1

1) No SKEY_VAL is not a variable.
2) This is my first attempt at using ODI, I did not create the SQL. All I did was to create a reverse a model against my MSSQL staging database and create and reverse a model against the planning application. Then I created an interface for the Account dimension in planning mapped the account, parent and description columns from my SQL table to the Planning dimension and I get this error. There are no columns called SKEY_VAL in either the source or the target and I have not created any objects with this name in ODI. I can see that ODI is asking for this column when I execute the interface, but I don't know why.
