E.2 Delta Watch List Configurations for the World-Check Watch List

Note:

These configurations are performed when you do not want to download the full watch list, and only want to download the delta watch list. This helps to reduce the download time and is not part of the screening process.

Transaction Filtering recommends that you always use the full watch list during the screening process. Due to the clustering strategy, which is implemented in the screening process, you must not download the delta watch list. There are certain cases in which you must download the delta watch list files, for example, if the full watch list files are not yet available for download or if you want to save time.

Customers who download the delta watch list files must first download the full watch list files and then download the delta watch list files. The delta watch list is then merged into the full watch list before screening.

The following image shows the information flow for the delta watch list:

When you download the full watch list, data is stored in the FSI_WC_WATCHLIST_INDIVIDUALS and FSI_WC_WATCHLIST_ENTITIES tables. When you download the delta watch list, data is first stored in the FSI_WC_WATCHLIST_DELTA_IND and FSI_WC_WATCHLIST_DELTA_ENT tables. Then the data is merged into the main table. For more information, see Merging the Delta Watch List to the Full Watch List.

Note:

You must always run the full watch list files before you run the delta watch list files. The full watch list files must be downloaded if, for example, the download of the delta watch list files has failed for multiple days. You can also run the full watch list once every week to ensure that the complete data has been processed.
