Hi Hari,
Customs Declaration is created as soon as a proforma invoice is created in the Feeder system provided you have the below settings already in Place.
- In Feeder system:-
- Control settings for Invoice (Application SD0C) for a particular invoice type needs to maintained and switched on
- In SAP GTS system:-
- Maintain the legal Regulation for Customs Declaration and activate it for particular (Import or Export) Scenario and for required country set/sets.
- Mapping and related Settings for Document from SAP Feeder system to SAP GTS Document ( in this case for Customs Declaration) needs to maintained in the SPRO-->General Settings area of the SAP GTS system. This includes both Document as well as Item Mappings.
- Maintain Numbering scheme for Tariff codes and assign those to the concerned Legal Regulation created earlier.
- Define Technical medium for messages for general documents and associated conditions in Customs Managemnt area to define the type of Declaration (Print or Electronic) to be used in this case
- Define Message Scheme and messages for Communication with Customs
- Define Control settings for Communication Process
- Define Determination of Activity sequence.
Above are the major steps involved for your query but these may further increase for more detailed configuration and as per the requirement.
Hope I answered it.
