Hello All -

I am desgining a parallel JOB and using a Column Generator in order to generate a Unique number but encountered an error in V8.5 during compilation.

Error : Stage 'CG_Unique_Number' requires a minimum of '1' non-reference inpu(s).

But as per the IBM Knowledge Center input link is optional.

http://www-01.ibm.com/support/knowledge ... stage.html

is anyone can explain the reason for the above error.

Basically a Column Generator stage adds columns to an input stream. It cannot generate rows out of thin air. For that you need a Row Generator stage.
