Updating User Information In Subscriptions Displays An Error
Symptoms
Updating user information in Subscriptions generates an error and doesn't allow you to save.
Cause
Errors generated when saving user information are caused by incorrect information. Other fields can be affected if their data was migrated to Arc XP.
Solution
Confirm the field you were updating and all other fields for that user are correct. It's possible that another field is causing the error, not the field you are updating.
