Overwrite the Created field for a Sharepoint list item

Sharepoint provides automatic fields, like « Created » that contains the creation date of a list item. It’s a readonly field.

You could use a webservice to change the ReadOnly property in order to overwrite its value.

Using SharepointPlus the code is:

// don't change the below information
// the details about this field are found using $SP().list().info
var updateSystemFields = "" +
    '' +
    '' +
    "" +
    "";
// send the request to the server
$SP().webService({
  webURL: "https://website.url.com/",
  service: "Lists",
  operation:"UpdateList",
  properties:{
    listName: "Name of the list",
    listProperties: "",
    updateFields: updateSystemFields,
    newFields: "",
    deleteFields: "",
    listVersion: "",
  }
})
