Rule 4. Add a Record Version that Intersects an Effective Period and Has an Extended Start Date

You can add a record version that intersects an effective period and has an extended start date.
If the following conditions exist, rule 4 applies:
  • The specified effective period intersects the effective period of an existing cross-reference record.
  • The changed period start date is later than the period start date of the existing cross-reference record.
Rule 4 ensures the following

behavior:
  • The period end date of the existing cross-reference version is updated with 'changed period start date - 1' in terms of the chosen timeline unit and the initial period start date is not changed.
  • A new version of the cross-reference record is inserted with the specified effective period.
The following image shows a cross-reference record with effective period that intersects the effective period of an existing cross-reference record and has a later period start date:
