Procedure

  1. Double-click tMap to open its Map editor.
  2. In the table representing the output flow (on the right side), enter StringHandling.DOWNCASE(row2.hashtag) in the Expression column. This automatically creates the map between the hashtag column of the input schema and the hashtag column of the output schema.
    Note that row2 in this expression is the ID of the input link to tMap. It can be labeled differently in the Job you are designing.
  3. Click Apply to validate these changes and click OK to close this editor.
