Before BR, Update - true

Condition: current.description.changes();

Choose the table name (Incident or Story, etc.) and field name (description) on the condition - as per your requirement.

(function executeRule(current, previous) { if (!current.description.changes()) return; var oldDesc = (previous.description || '').trim(); var newDesc = (current.description || '').trim(); function tokenize(text) { return text .replace(/\r\n/g, '\n') .split(/(\n+)/) .map(function(chunk) { return chunk.match(/\n+$/) ? chunk : chunk.trim().split(/\s+/); }) .reduce(function(a, b) { return a.concat(b); }, []) .filter(function(w) { return w !== ''; }); } var oldWords = tokenize(oldDesc), newWords = tokenize(newDesc), m = oldWords.length, n = newWords.length; // LCS matrix var L = []; for (var i = 0; i <= m; i++) L[i] = Array(n + 1).fill(0); for (i = m - 1; i >= 0; i--) { for (var j = n - 1; j >= 0; j--) { L[i][j] = oldWords[i] === newWords[j] ? L[i + 1][j + 1] + 1 : Math.max(L[i + 1][j], L[i][j + 1]); } } // Backtrack into diff var ops = [], i = 0, j = 0; while (i < m || j < n) { if (i < m && j < n && oldWords[i] === newWords[j]) { ops.push({ op: 'equal', word: oldWords[i] }); i++; j++; } else if (j < n && (i === m || L[i][j + 1] >= L[i + 1][j])) { ops.push({ op: 'insert', word: newWords[j] }); j++; } else { ops.push({ op: 'delete', word: oldWords[i] }); i++; } } // Format spans var newHtml = '', oldHtml = ''; ops.forEach(function(o) { if (o.op === 'equal') { newHtml += o.word + ' '; oldHtml += o.word + ' '; } else if (o.op === 'insert') { newHtml += '' + o.word + ' '; } else if (o.op === 'delete') { oldHtml += '' + o.word + ' '; } }); // Timestamps var newTimestamp = new GlideDateTime().getDisplayValue(); // now var oldTimestamp = previous.sys_updated_on.getDisplayValue(); // when previous was saved // Build output with labeled timestamps var journalHtml = '[code]' + '

' + '' + '
' + '' + '
' + '' + '' + '[/code]'; // Write to work notes (respects journal + HTML rendering) current.work_notes = journalHtml; })(current, previous);

OUTPUT:

OUTPUT AFTER IMPROVISATION:

Fig: Differentiate Work notes with timestamp

Note - The reason why we didn't fetch the input from Work notes rather choose a string field (Description) as input and performed the required HTML operation on it, and then output it into a journal entry field like 'Work notes' is because we don't want to alter the very basic structure of the journal entry field 'Work notes' here. I have rather chose 'Work notes' just as a medium to display the formatted string, which ultimately serves the purpose.
