    Replace field value?

      I load data into Fact table from our ERP system and I have a field called Payer.  I then Left Join to Fact data in a spreadsheet that has the fields Payer and Exclude.  The Exclude field will have the value of 'Y' in it.  Now  the Exclude field in Fact will have a 'Y' or it will be Null.

       

      My Question:

      After I have done the above (Fact table is now loaded with Payer and Exclude fields, I want to go through a differnet logic process, something like if Payer = X and some other field = Z Change the Exclude field from Y to N.  Is there a way to overwrite the value of a field?

       

      Thanks,
