I am facing a strange issue in setting permission in current list item. I am querying users form a different list based on some conditions and trying to provide the permission to that user. There is an option to remove existing permission in set permission task. whenever i check that check box and run the workflow, it is removing the access of that user from the site. I want to set item level permission that will be accessible to some users but do not want to revoke the access from the site. Can anyone help e with regard. Your help will be much appreciated.
