When a project containing an Index Load component is fully configured you can simulate the incremental load:
To run the project, select Run | Trace. All records matching the condition specified by the Load Index Value property are processed.
Select to perform post-processing for a successful execution. Click Yes.
Simulate the project or the Index Load component again. The Index Load component does not return any records. See “Simulating a project”.
You can manually update the source table between step 1 and 2 to verify that the correct modified records are retrieved.
To simulate again, right-click the component and select Reset Load Index Value, or, in the Properties window, enter a new value for the Load Index Value property.
