Example of Hard Delete Detection for Direct Delete

Example of Hard Delete Detection for Direct Delete

Your organization has a single source system that supplies data to a base object record. You need to detect hard deletes in the source system to flag the base object record as deleted. The source system deletes a record, reactivates the record, and then deletes the reactivated record. The
MDM Hub
 accordingly flags the source record as deleted and end dated.

Records Before Hard Delete Detection

Before the
MDM Hub
 detects hard deletes in the source system, the delete flag for the base object record and the cross-reference record is active.

Records When Hard Delete Is Detected In the Source

When there is a hard delete in a source system, the
MDM Hub
 performs the following tasks:
  1. Detects records that are deleted by comparing the landing table to the previous landing table.
  2. Reinserts the column values for the deleted records into the landing table along with a delete flag and the end date.
  3. Updates the cross-reference record as inactive with an end date.
The end date contains the system date or the date that you provide when you determine the end date value.

MDM Hub
