Import Staff Error


When I try to import Staff on the database I receive the following error:

"3 (-1) Failed to insert or update database record. "

I’m not sure what that means. Any advise? I’m using only Person (username) and Type (teaching) which are the only required fields.

I fixed it by adding something on the “initials” field. It seems that although it isn’t required, on the database it requires “NULL” or it will fail.
