Hi Regula,

The mentioned scenario can be achieved by by-passing the User ID which is used for data import via Data Loader  in the validation rule.

For Eg.: Use ” $User.Id = ‘00532000000OqwAWQS’ ” and define the User ID for which the rule needs to be by-passed and place it logically in the validation rule.

Thanks & Regards

@subham Can you please elaborate the scenario.

As the problem statement, use OrderBy LastModifiedDate ASC in the Query while displaying the List of Contacts.
