The evidence change history entity is used to store information regarding all maintenance operations performed on a piece of evidence. When evidence is captured for the first time, it is assigned a correction set ID. The system uses the correction set ID to track the changes made to the same evidence.
By using the correction set ID, the system can track evidence changes across multiple evidence records. When changes are made to an active evidence record, the system creates a new in edit evidence record. This protects the evidence information used in eligibility and entitlement determination. Both the active and its in edit evidence record share the same correction set ID; therefore, the evidence change history will include information about the active evidence and about changes made to it post-activation.
The following is the complete list of evidence changes that get recorded in the evidence change history:
The following table describes each of the attributes in the evidence change history entity:
Attribute | Description |
---|---|
Evidence Change History ID | Unique identifier of the evidence change history record. This is the primary key used to identify the evidence change history record in the system. |
Evidence Descriptor ID | Identifier of the related evidence descriptor record. The correction set ID is retrieved from this evidence descriptor record. |
Change Type | Type of change that has occurred. This is a code table value. The change types include "input", "modified", "removed", "modification activated", "removal activated", etc. |
Change Date Time | Date on which the evidence change is captured. This is the current date and time on the system when the change occurs. For example, when the evidence is first captured, the current date and time on the system is recorded. |
Change User | User who performed the change on the evidence, e.g., the user who first captured the evidence on the system. |
