Starting
of Dangerous Goods Checks in Shipment Documents 
This function starts dangerous goods checks in shipment documents.
See “Prerequisites“ in Dangerous Goods Checks in Shipment Documents.
You can start dangerous goods checks in shipment documents in several ways:
· Automatic start
If dangerous goods checks are activated, the system starts dangerous goods checks automatically when you save a shipment document and it has the status Planned. If you have set up a dangerous goods check schema for the current context, the system performs it. Dangerous goods checks are not started if a shipment document is being processed that was already in the database with the status Trsp.processing. Shipment documents that have this status in the current transaction are checked.

You activate dangerous goods checks in the IMG activity Activate Dangerous Goods Checks in Customizing for Dangerous Goods Management. In the IMG activity Assign DG Check Schemas for Shipment Documents, you specify the context in which check schemas should be used.
You can create more than one shipment document during one transaction. When you save your entries, all documents are checked. As the deliveries for a shipment or the dangerous goods master data could have changed since the last check, shipment documents that were not changed are also checked.
You can only assign a new status for shipment documents if the status Planned already exists. The system thus guarantees that shipment documents always reach the status Planned, and that dangerous goods checks cannot be bypassed.
· Manual start
If dangerous goods checks are activated, you can start them manually at any time, regardless of document status. Choose Edit ® Dangerous goods check, in (for example):
¡ Shipment header for General data
¡ Overview screen for selected shipments
If you have set up a check schema, the system performs it. If no check schema has been set up, a message is displayed.
· Automatic start in collective processing
The dangerous goods checks are started in the same way for documents with status Planned in collective processing. If you have set up a check schema, the system performs it.
