In case you ran into this, you're not crazy: Data Loader 21 needs every field to be mapped during an insert/update/upsert/delete. This is a bug, and it's being worked on. In the meantime, use Data Loader 20. I've posted the Data Loader 20 installer here: http://tinyurl.com/DataLoader20 UPDATE, 2011-04-30: This bug has been fixed. |
