Testing a mapping

After you complete a mapping and you confirm that the mapping is valid, you can perform a test run to verify the results of the mapping. Perform a test run of a valid mapping to verify the results of the mapping before you create a mapping task.
When you perform a test run, you run a temporary mapping task. The task reads source data, writes target data, and performs all calculations in the data flow. Data Integration discards the temporary task after the test run.
You can perform a test run from the Mapping Designer or from the Explore page.
To test run a mapping from the Mapping Designer, perform the following steps:
  1. 1. After you save the mapping, click Run.
  2. 2. Select the runtime environment and specify values for parameters, if any parameters are in mapping.
  3. 3. Click Run.
To test run a mapping from the Explore page, perform the following steps:
  1. 1. Navigate to the mapping and in the row that contains the mapping, click Actions and select Run.
  2. 2. Select the runtime environment and then click Run.
Note that if you select New Mapping Task instead of Run, Data Integration creates a mapping task and saves it in the location you specify. For more information about mapping tasks, see Tasks.
