In the

Properties

view, click the

Advanced

tab.

Select

Create or replace table at run-time

The following image shows the

Create or replace table at run-time

option in the Advanced tab of the target object: To configure a Write transformation to create or replace the target table at run time, select the option in the Advanced tab.

To configure a Write transformation to create or replace the target table at run time, select the option in the Advanced tab.

At run-time, the Data Integration Service creates, or drops and replaces, the target table.

When a mapping contains multiple targets whose columns are defined by the same physical data object, enable the

Create and replace table at run-time

option for only one of the targets. If you enable this option for more than one target, the metadata of the table that the mapping creates would match only one of the targets, and the mapping fails.
