How to supplement 'External Document No' in a Posted Invoice


I have some problem now,

1、 I have posted the invoice a long time ago,but now i find out that the ‘external document no’ is blank,so do i can supplement the ‘Exernal Document No’.

2、The purchase invoice will be receipted after three months,how can i do?Can i enter an wrong invoice(the content is same as the right invoice)? and then enter an credit memos when the right invoice comes here.

Thanks in advance!

Hi Nancy,

The answer is very easy: You can never change a posted document in Navision.

The only right way to do this that will keep your government and auditor happy is to create a credit memo for the wrong document and then a new invoice with the correct information.


I see,Thanks a lot!
