Supplementary customs declaration and Import code number

Hi guys,

I've a question from my colleagues from export/import...

They are working with the Supplementary customs declaration. Now it can happen that the Import code number change in the time when starting with the declaration and until sending it to the customs authority. So it can happen, that the "old" number is still in the document.

Custom authority say, that we have to send it with the new number. But also if you're in change mode in the Supplementary customs declaration it isn't possible to change the Import code number.

Any idea?

Thank you in advance.

Kind regards

Thomas
