Use the URL parameter ‘saveURL2’ to redirect the user to the native edit page. This parameter accepts a URL encoded string of the native edit page, and ‘newid’ will be replaced with the created record’s Id.
The value of the saveURL2 parameter below ‘%2F%5Bnewid%5D%2Fe%3FretURL%3D%2F%5Bnewid%5D’ is a URL encoded string of ‘/[newid]/e?retURL=/[newid]’. On saving the new cloned record, the ‘[newid]’ value will be replaced with the new record id, and the native edit page will load with a location like ‘https://na1.salesforce.com/006380000012345/?e?retURL=/006380000012345’.
