How to Configure Differential or Delta Load DEM Rules

Tip Once the “Initial Load” or “Data Load” of the CI data is completedwe recommend applying Differential or 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 or 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. The recommended best practice is to select the Delete Record option for CI Relationships, and select the Update record to the selected status option for CIs.
