As I’ve noted before, cloning records in Salesforce is simple and powerful option when quickly creating similar records, but sometimes you need to go deeper. If you need to clone a record only including certain values in your clone, or bring in items from the related lists, you’re in for some annoying Apex code. Or you could check out Super Clone!
Super Clone allows administrators to create configurations for how records will be cloned, edited, and copied. Field values can be specified, cleared, or cloned. Related lists can be included, and configurations may be set for their fields as well.
This powerful, free app has been around for a while. Feedback is mostly very positive, and support is incredible. I strongly recommend checking out this awesome app!
