Data Integration

displays preview results on the

Preview

panel of the selected transformation and each upstream transformation.

Data Integration

does not display preview results for downstream transformations.

If a transformation has multiple output groups and you want to preview results for a different output group, select the output group from the Output Groups menu at the top of the

Preview

panel.

To download preview results, click

Download

on the

Preview

panel.

Data Integration

stores preview results in CSV files on the Secure Agent machine. When you run a preview,

Data Integration

creates one CSV file for the selected transformation and one CSV file for every upstream transformation in the mapping. If a transformation has multiple output groups,

Data Integration

creates one CSV file for each output group. If you run the same preview multiple times,

Data Integration

overwrites the CSV files.

By default, the files are stored in the following directory:

<Secure Agent installation directory>/apps/Data_Integration_Server/data/cache/preview

The CSV files are stored in this directory unless an organization administrator changes the value of the $PMCacheDir property for the Data Integration Server service that runs on the Secure Agent. For more information about Secure Agent services,

see the

Administrator

help

.

Data Integration

purges the preview directory once every 24 hours. During the purge,

Data Integration

deletes files that are more than 24 hours old.
