Our application has Integration to external system where the external system updates account records every 5 minutes. Let us say I am editing an account record in the Salesforce Ui and if the same account gets updated by external system then will there be any error, i.e. if update happens to an Account record at the same time both in the Salesforce UI and from the external system, will it throw any error. Can we do anything to avoid exceptions in such situations. Is it possible to prioritize the external system update avoiding error/exception? Please clarify.
Thanks in advance!
