Subj:   Re: How records get hashed if PI value is NULL?
From:   abhishek.gupta

As per Teradata 13 manuals:

Without a PI, the hash value as well as AMP ownership of a row is arbitrary. Within the AMP, there are no row-ordering constraints and therefore rows can be appended to the end of the table as if it were a spool table. Each row in a NoPI table has a hash bucket value that is internally generated.
