ds_uvput() - Write failed for record id '<Missing or NULL

[SonShe]

I get the warning message ds_uvput() - Write failed for record id '<Missing or NULL>'. In this job I have a hash file as the input, a hash file being used for lookup and then another hash file to write the data. I have about 4000 rows in the input. The lookup criteria is satisfied by about 250 records. I don't have any constraint to drop records when not found in the look up. But I am loosing records!

Please help me understand what is the warning message trying to say.

Thanks for help

You are writing records with null key fields to a hash file, and that is a Bad Thing.
