The example builds a string from the name of the parent record, the name of this record, and the memo of this record. {createdfrom} || ' ' || {name} || ' ' || {memo}

The following example combines several of the techniques covered here. It puts a hyperlink in a custom formatted column which, when clicked, opens the sales order record associated with a row.
