Microsoft Dynamics NAV 2013 R2 - "Tax Document not Found" error
Overview
The issue is occurring when the customer is calling the Sales Post process from code
Environment
The environment is NAV 2013 R2
Resolution
The resolution is when the customer chooses to use the Posting Description of the Sales Document as anything other than "Document Type + space + Document No.", Avalara receives the error. I cannot determine where in the code this occurs, so I am assuming the field is passed through some variable.
However, when I use the standard setting of the field, it will post. I've modified the documents being created to use the standard setting, rather than using this to tie together the multiple billings from a single subscription.
Cause
The cause is when the customer chooses to use the Posting Description of the Sales Document as anything other than "Document Type + space + Document No.", Avalara receives the error
