 Business Rules
 
 | 
- If there is not a User name column specified, User name mask can be used as an alternative method.
 
- User name mask is any legal character (a-Z, 1-2, underscore and dash) followed by the key/tag {0}. This tag will be replaced by the ID of the newly created user. Example of a user name mask is 'CoolUser{0}'.
 
- If even User name mask is not supplied, then the default mask in the system – that is ‘CAT{0}’, will be used as the user name mask for all imported Users, where {0} is the newly created Id of imported user in the system.
 
- New user name is created only when you are not updating an existing user in your database.
 
- The field used to identify updates of existing user is user_id. In other words, if user_id is specified in your excel then the user name will not be used.

 Auto mapping
 
 | 
 In order to ensure auto mapping then the column name in the Excel must fit with the given name in import. This name is language dependent as shown: 
 UK: User_Username
 DK: Bruger_Brugernavn

 Validation

- User names may not contain the characters [ / ] and [ . ]. Error type: ERROR(the import job will not be allowed to be executed)
 
- User names should be between 6 and 50 characters. Error type: ERROR(the import job will not be allowed to be executed)

 Notes
 
 | 
 If you are importing to a new user and the user name is empty a user name will automatically be created for the user. 
 As explained above, the priority of which user names will be applied are:
 
- Highest: Existing users will always keep their existing user name
 
- Second: New users will get a user name based on mapped column
 
- Third: New users will get a user name based on mask
 
- Last: New users will get an system generated user names
