Hi,

I've published the model and packages already.  But I need to add more database columns to the existing Query Subject.

I tried using the ..Run Metadata Wizard, but it's creating another object itself by adding these new columns, instead of adding to the existing object.

Any help would be appreciated.

Thanks

Right click on the query subject and create a 'Query Item', then edit the expression to what you need.

But it throwing an error. Because the column I'm referring doesn't exist in the Query Subject yet.

QE-DEF-0030 Expression parsing error.
QE-DEF-0359 The query contains a reference to at least one object '[dbo].[tbl_PO_Facts_POReceipts].[POLineRef]' that does not exist.

I see.
1st of all, cognos best practice suggests that you bring everything from database in your source view and then create business view from the source by selecting only what is needed.
In your case, double click on the query subject you want to add a column, then expand database tables and drag the column what you want to bring in.
Click OK and you'll see the new columns.

It's silly one.  I removed the Select * from table in the Query Subject Definition and re-wrote the same query. It works.  

Always, thanks for your help
