DSXchange

I m trying to run the Ds job through Reference_MAtch stage .
i have to compare two columns(data and reference) and get the percentage of match for all the records.
But i am receiving as FATAl ERROr as "main_program: Fatal Error: Field not found: keyChange"

Can anyone suggest on this .

See answer to your other post. A column called keyChange is usually the result of a Sort stage.

I have taken two column from two seprate files to compare through reference match stage.

I have used CHAr comparision with m prob as 0.66 and u prob as 0.33
I have only one column in both the files and i have not used the block command.

What is parameter which need to be defined

You must have at least one blocking field. Even if it's a constant in each file.

Do i need to give Weight Override, and Cut off values
