Deleting mapping last scan history

When Integration Composer executes a mapping for the first time, it copies the last scan date for top-level objects in the source data source (for example, Client in Centennial and System Architecture in SMS) into the Integration Composer repository.

About this task

Integration Composer compares the last scan date in the Integration Composer repository with the scan date in the source data source and performs one of the following actions:

  • If the date for an object in the source is earlier than or is the same as the last scan date in the repository, Integration Composer skips the source instance.
  • If the date for an object in the source occurs after the last scan date in the repository, Integration Composer processes the expressions for the source instance and updates the last scan date in the repository.

By doing this, Integration Composer ensures that it transfers only the data that has changed since the last scan date.

If you modify a mapping and you want to implement the change, you might want all data transferred. To accomplish this, you must delete the last scan history.

Procedure

  1. In the Integration Composer window, choose Delete Mapping Last Scan History.
  2. Select one or more mappings for which you want to delete the last scan history by clicking the mapping.
    1. To select a series of mappings, use Shift+click.
    2. To select separate mappings, use Ctrl+click.
    3. To select all mappings in the list, click Select All.
    4. To cancel the selection of all mappings in the list, click Deselect All.
  3. After selecting one or more mappings, click Delete and, in the Delete Mapping Last Scan History dialog box, click Yes.
