Maintaining the Dangerous Goods Master 
Purpose
The dangerous goods master delivers all dangerous goods specific data in the R/3 System centrally.
The following components require data contained in the dangerous goods master:
Dangerous Goods Checks
Dangerous Goods Papers
As the dangerous goods master is linked to the material master, you can only create dangerous goods master records for existing material master records.
Process flow
If you create a dangerous goods master, you must first allocate the dangerous goods master data record a material and a dangerous goods regulation. The system uses these entries to generate the logical key for the newly created dangerous goods master.
- You link the dangerous goods master with the selected material master by allocating the relevant material to the dangerous goods master.
- Materials and dangerous goods regulations are the deciding parameters for dangerous goods checks and the generation of transport papers. Dangerous goods regulations consist of mode of transport categories and validity areas.

You can use the engineering change management functions in the component dangerous goods master. For further information about engineering change management, see Help
