title: Data objects unicode in popup ABAP
body: <p>I have the next problem to show a popup AVL. My error is the next:<br>
  <strong>The statement</strong><br>
  "MOVE src TO dst"<br>
  requires that the operands "dst" and "src" are convertible.<br>
  Since this statement is in a Unicode program, the special conversion<br>
  rules for Unicode programs apply.<br>
  In this case, these rules were violated.<br><br>
  <strong>My code is the next:</strong></p>
