Hi Ankit, Thank you for posting your concern.
If you want to add a new criterion, you need to use the 'ADD' operator in order to do it. However, please note the old criterion will not be removed automatically when you will add a new criterion. Furthermore, you need to use the CampaignCriterionService as well, set the operator as 'REMOVE' and specify the criterion ID in the id field to remove the specific criterion of campaign and the same way with operator as "SET" so that the API will know the criterion you want to update/remove. Let me know if you have questions/clarifications.
