If this information helps, please mark the answer as best. Thank you
I would suggest you use this on the user trigger, I have used a boolean field 'assign_permission__c' on user object.
Supposingly you will need to make few changes according to your requirement:
if(trigger.isupdate) { if(trigger.isafter) { List<PermissionSetAssignment> permissionSetinsertList = new List<PermissionSetAssignment>(); list<id> lstuseridtoberemoved = new list<id>(); list<PermissionSet> permissionstobeassigned = [SELECT Id, Label FROM PermissionSet WHERE Label = 'ReadEditPermissionset']; for(User u: trigger.new) { boolean oldstate = trigger.oldmap.get(u.id).assign_permission__c; if(u.assign_permission__c != oldstate && u.assign_permission__c == true) { PermissionSetAssignment psa = new PermissionSetAssignment(PermissionSetId = permissionstobeassigned[0].id , AssigneeId = u.Id); permissionSetinsertList.add(psa); } else if(u.assign_permission__c != oldstate && u.assign_permission__c == false) { lstuseridtoberemoved.add(u.id); } } if(permissionSetinsertList.size()>0) { insert permissionSetinsertList; } if(lstuseridtoberemoved.size()>0) { delete [SELECT Id from PermissionSetAssignment WHERE PermissionSetId = : permissionstobeassigned[0].id AND AssigneeId in : lstuseridtoberemoved]; } } }Thanks
