Error when bulk updating FND_TIMEZONE profile values

Hi team,

we're tying to bulk update time zone preference for users. We're using the exact same template found here: and this is the one i'm loading.

ProfileOptionCode	LevelName	UserName	ProfileOptionValue
FND_TIMEZONE	USER	email@xxxx	Arizona

I load the csv file in "File Import and Export" with account "hcm/common/content" then I go to "administrator profile values" and i select import in the profile option values but this is the error i get in the log file: "ERROR: Invalid header column present : ProfileOptionCode".

Can anyone help me?

Thank you,

Claudia
