Before you begin

When processing data flows using a tMap, if the input and output columns across a mapping are of different data types, compiling errors may occur at the Job execution time. The Enable Auto-Conversion of types option in the tMap helps avoid such errors.

To enable this feature in tMap in a Job:


  1. Click the button at the top of the Map Editor to open the Property Settings dialog box.
  2. Select the Enable Auto-Conversion of types check box and then click OK.

What to do next

You can activate the automatic conversion option at the project level so that any tMap component added afterwards in the project will have this feature enabled.
