Reordering a preparation step

In Talend Data Preparation, each preparation step you apply on your data is based on the previous one. As a consequence, if you already applied many preparation steps to your data, but forgot one small change at the beginning, you would not achieve the expected result.

In a preparation with many steps, you have the possibility to rearrange your preparation steps so that the changes take effect in the right order.

In the earlier steps, you have performed a lookup on the State column just before making a correction to this column, where the Texas entry was in the wrong format. Because that last change on the State column was performed after the lookup, some information is now missing from the Region column that was added with the lookup.

You are going to take the lookup step and place it as the last step of the preparation to make sure it includes all the States.


  1. Point your mouse over the lookup step.
  2. To move the lookup step from the second-last position to the last position, you can:
    • Drag the recipe step and drop it at the bottom of your recipe.

      the grey line shows where the recipe will be placed.

    • Click the up arrow on the left of your recipe step to move it down.


Your preparation is automatically updated with the correct sequence of actions, and the Region column now includes Texas.
