User's username truncates to 40 Characters during importIssue You will recognize this issue if you are attempting to import Users into the instance and the users have user names over 40 characters in length. When the import is completed the user names are truncated at 40 characters.CauseWhen the import is carried out the records are added to the staging table (or Import Set table) prior to being transformed into the sys_user table. The OOB max length value for the username field in this table is 40. Thus usernames are truncated to 40 characters in the source table for the transform, which was then carried over to the sys_user table.ResolutionIncrease the Max Length value for the Import Set field that transforms into the User's username [sys_user.user_name] field.Related LinksNote that this is similar to KB0955103. However KB0955103 is for the email field and this KB is for the user name field.
