Reproducing the Issue

  • Post Refresh in Target Instance, search for a user in Global Search and you will see "-" in the users names.
  • In Target Instance User Data File (UDF), First Name , Last name is only showing the value "-" (hyphen).


As per our engineering, this is an expected behavior.


Our engineering team has reviewed and analyzed the data from the database and found that this is an expected behavior related to the Data Anonymization feature and Shuffling Column Values selected. Some users' First Name and Last Name fields in the source instance contain a hyphen ("-"), which was also copied to the target instance after the refresh. The Data Anonymization algorithm shuffles column values for users' names, which means that the actual value of a user in a table can take the value of some other user from the same column. To avoid similar issues in the future, we recommend correcting any data inconsistencies in the source instance itself. 

Note: Data anonymization will be completed irrespective data user's status i.e. valid/Invalid

Please note that with data anonymization the same first name/last name can be used in more than one column after the data anonymization is completed.

For Example, it can look like this:

Before Anonyimization:

  • First Name
    • Mary
    • Jane
    • Anne

After Anonyimization:

  • First Name
    • Mary
    • Mary
    • Mary
