Hello,

I have a lead, whcih i shared mannually to a user by apex code using/
below link.
https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_bulk_sharing_creating_with_apex.htm

I can also see that lead is shared with user.
But when user see it it shows inssufiecuient proveliges.

what can be reason ?

I am trying to populate Notes_Preview__c on Description for event.
However it is not populating.

trigger:

if(trigger.isAfter ){
            if(trigger.isInsert || trigger.isUpdate ){
            EventTriggerUtil.updateDescription(trigger.new);
            }

class:
private static boolean Hassent = false;
    public void updateDescription(List<Event> eventList){
        List<Event> eventtoupdate = new List<Event>();
        If(!HasSent){
        for(event e:eventList){
            Event eve =new Event(Id = e.Id);
            eve.Description=eve.Notes_Preview__c;
            eventtoupdate.add(eve);
            HasSent=true;
        }
        }
        if(eventtoupdate.size()>0){
            update eventtoupdate;
        }
    
        
    }
