Any additions, modifications, and deletions of a contract revision line item will be logged if the Audit Trail indicator is enabled on the contract revision.
When a new revision is created, a history logging will not be created for the creation of the new revision. However, when an item is modified, the changed values are copied to the Sales Contract Change History page. Only the columns that have been changed will contain values; all other columns will be empty. History logging will only occur when additions, modifications, or deletions are made and the prerequisites for logging the changes are fulfilled.
Note that if the Audit Trail is enabled, Contract Change Order Required and Change Comment Required will also be selected by default. The change order and change comment will be added to the history along with the item that was added, modified, or removed.
