You use change numbers to create or change data records if the data record is not to be valid for the whole system period.
If you want to work without change numbers, the validity period of the dangerous goods master records created runs from 01/01/0001 through 12/31/9999.
If you want to work with change numbers, you can:
Create dangerous goods master records with a key date
Run a data record split on existing dangerous goods master records on a key date
When a dangerous goods master record is split, its corresponding packaging data records are not split automatically as well. However, you can split packaging data records separately with the same or a different change number.
If you enter a change number as a selection criterion to select dangerous goods master records, the system selects

For each dangerous goods master record, the packaging data records are selected whose validity period overlaps with the validity period of the dangerous goods master record.
