field from input dataset '-1' is NULL. Record dropped

[bobyon]

I've just received the following error in a Trasnsform stage:

Code: Select all

Xfm,5: Field 'HOURS_FLAG' from input dataset '-1' is NULL. Record dropped.

The problem was resolved with a simple restart of the job, but, I don't recall seeing "dataset '-1'" before.

What would the '-1' represent

The job is a simple:
ODBC_conn -----> TX -----> DB2_conn

There were no funky derivations on the 'HOURS_FLAG' column, just mapped straight through.
