[Bydesign]Can we adjust Tax net base amount in customs duty invoice?

Dear Experts,

Customer is facing an issue as in the customs duty invoice on Bydesign, Import VAT Debit Item in Basic data - we can only key in VAT amount (let's say 18,260) which would automatically calculate the Tax net base amount as 182,600 based on the formula - VAT amount multiplied by 10%.

However, in normal Korean Business cases, there are many scenarios where Tax net base amount is not exactly matching as per the formula due to the rounding off. In other words, as explained above example - the Tax net base amount should be changed as 182,610 instead.

So I am wondering whether we have an option to change this Tax net base amount on the customs duty invoice itself.

I tried from my side but it seems that system does not allow the difference to post.

Any workaround we can think of please as there are so many cases in Korea.

And in order to report VAT, this must be adjusted.

Thank you so much for the reply.

Best regards,

Yohan Oh
