Error Message: 'Item cannot be saved, because another user has changed it after you opened it.'
I am experiencing the error message above when trying to submit an email (with attachment) as an update to a call. Our web interface allows a user to create new calls or update existing calls with the option of adding an attachment. When a call is created or updated the call information is passed using the web api; if an attachment exists this is then emailed as an update to the call. In some circumstances the emailed attachment is failing. We have a number of database rules which run when a call is created/amended. One theory we have is that the database rules are still running when the attachment is mailed to the server causing a conflict. Is there anyway of telling whether a call is ready to receive an attachment? Can anyone think of a more elegant solution to adding an attachment to a call (using the web api between two boxes)?

Thanks for the information and link. Unfortunately I am unable to view that document at present as my passport account doesn't seem to have sufficent permission. I should have also said in my original post we are running Service Desk 4.5 (SP 15).
