title: How to update internal table without using MODIFY?
body: <p>I have created internal tables where I want to update age of employee in one internal table by calculating it from another table, I have done arithmetic calculations to get age but now how can I update it by any alternate way instead of <code>MODIFY</code>?</p>
  <pre><code>WRITE : / 'FirstName','LastName', '  Age'.  
  LOOP AT gt_items1 INTO gwa_items1.
    READ TABLE gt_header INTO gwa_header WITH KEY empid = gwa_items1-empid.
    gwa_items1-age = gv_date+0(4) - gwa_header-bdate+0(4).
          
    MODIFY gt_items1 from gwa_items1 TRANSPORTING age WHERE empid = gwa_items1-empid.
    WRITE : /  gwa_items1-fname , gwa_items1-lname , gwa_items1-age .
  ENDLOOP.
  </code></pre>
