Checking of Validity Areas 
For the dangerous goods checks and when creating dangerous goods documents, you must ensure that the correct dangerous goods regulation is applied for each phase of a dangerous goods transport.
By checking the validity areas, the system ensures that no dangerous goods master records can be created that could lead to any ambiguities when determining the relevant dangerous goods regulation.
Dangerous goods master records are stored in the system as a combination of material and dangerous goods regulation.
A validity area and a mode-of-transport category are then assigned to the dangerous goods regulations in Customizing for Dangerous Goods Management in the IMG activity Specify Dangerous Goods Regulations.

In the system you can create validity areas at five geographical levels.

The system first searches for the regulation for the required mode-of-transport category at the lowest geographical level.

Material 01 is to be transported in France.
If, as in the table above, no dangerous goods master record with a regulation for the validity area France is available at regional to national level, the dangerous goods master record with material 01 and the dangerous goods regulation Road-WE (Western Europe that includes France) is used.
When you create a new dangerous goods master record, the system checks whether dangerous goods master records already exist for the same material. If a dangerous goods master record exists with a regulation whose validity area overlaps with the validity area of the regulation for the new dangerous goods master record at the same geographical level, the system refuses to create a new dangerous goods master record.

If the dangerous goods master records Mat.01, Road-CE and Mat.01, Road-SW could exist alongside each other, it would not be possible to determine exactly which dangerous goods regulation should be used for a transport through France.

The dangerous goods master records Mat.01, Road-CE and Mat.01, Road-France can both exist alongside each other because a clear decision would be needed here in the case of a transport through France as a result of the concept of the more localized validity area.
When creating a dangerous goods master record, the system also takes into account whether the new dangerous goods master record is separate in time from existing dangerous goods master records. This means a possible overlap is not interpreted as such if the validity periods of the two dangerous goods master records do not overlap. See also: Working with Change Numbers .
If dangerous goods master records exist for the same material with dangerous goods regulations whose validity areas overlap, but which are assigned to different mode-of-transport categories, the regulation with the required, more exactly defined mode-of-transport category is always used.

For road transport in France, from the above selection the regulation Road-CE would be used.
