Hi Olaf,
You don't mention which Legal Regulation you are using, so I assume that you've set up your own localisation for a non-standard country?
In the IMG, take a look at the "Duty Structure for Exports" for Legal Regulation 'ACE' (because it's simple, and sits at the top of the list). The IMG path, in case you don't know, is:
- Customs Management
- > Calculation of Customs Duty
- >> Define Customs Duty Framework
Start off by copying those same Duty Types (A001 - 3), C100 & W001) for your own Legal Regulation.
Then create a new Export Declaration. This time, you will see that the Duty Types are shown in header and item. You'll be able to enter the Goods Value in the item, and the Transport & Insurance costs at the header.
If you create the Declaration by transferring a proforma from ERP, the Goods Value should be populated automatically.
Hopefully that will get you started. If you have further questions, then come back to us.
Regards,
Dave
