How to Configure Differential/Delta Load DEM Rules

Tip Once the “Initial Load” or “Data Load” of the CI data is completedwe recommend applying Differential/Delta Load settings. These settings apply to all data loaded from UCMDB to SM.

These loads send only updates regarding modifications discovered in the IT infrastructure from UCMDB to SM.

To set up the SM DEM Rules for Differential/Delta Loads:

  1. Log in to Service Manager as a system administrator.
  2. Navigate to Tailoring > Web Services > Discovered Event Manager Rules.
  3. Press Enter or click the Search button.

    A list of all the Discovered Event Manager Rules in SM is displayed.

  4. For each of the Discovered Event Manager Rules, perform the following steps:
    1. Select the relevant Discovered Event Manager Rule.
    2. In the “Action if matching record does not exist” section, select the appropriate action required for each newly detected CI. If uncertain, select the Add the record option.
    3. In the “Action if record does exist but unexpected data discovered” section, select the appropriate action for each CI that was modified, resulting in an unexpected or incorrect result. The recommended best practice is to select the Open a Change option.
    4. In the “Action if record is to be deleted” section, select the appropriate action required for each CI that was removed/deleted. The recommended best practice is to select the Delete Record option for CI Relationship, and select the Update record to the selected status option for CI.
    5. Save the Discovered Event Manager Rule record.
