title: Salesforce: Update Managed Object's Auto number Field...
body: <p>I would like to know if we can update auto number field. When I tried updating using Dev Console system said : 'Field is not Writable'<h1></h1>
  In our support product(Managed Package), I need to update/ start auto number field from specific number say 100.<h1></h1></p>
  
  <p>I am thinking of creating a text field and imitate is as that Auto Number field. But I don't know how much will it hamper existing functionality of the package.</p>
  
  <p>Any idea.</p>
  
  <p>Thanks in advance.</p>
