Hi Suresh,
Thank you for reaching out.
The EntityNotFound.INVALID_ID occurs when ID of the entity you are operating on isn't valid. In your scenario, most likely any one of AdGroup ID, Campaign ID or Keyword ID doesn't exist in your account. With this, I would recommend you to check if the specified IDs are indeed exist using CampaignService.get(), AdGroupService.get() and AdGroupCriterionService.get().
After checking this and if the issue still persists, so I can further investigate the issue, could you provide the complete SOAP request and response logs via Reply privately to author?
