Frequently Asked Questions¶

Q: Why isn't the OSS field being set on a new sales order?
A: Check that the OSS field is enabled on the Customer Card. Also verify that a matching row exists in VAT Setup for OSS for the combination of origin country (company or location country) and the customer's ship-to country.

Q: The VAT Business Posting Group is not being updated when I change the ship-to address.
A: Ensure the OSS flag is enabled on the document header, and that the ship-to country matches a row in VAT Setup for OSS.

Q: An item line is not getting the correct VAT Product Posting Group.
A: Check Item VAT Setup for OSS for the item + destination country + posting date combination, and verify that a matching row also exists in Item VAT Rate Setup for OSS for the resolved VAT %.

Q: The Suggest Lines action says it found no lines.
A: Confirm that at least one VAT Statement Line in the selected template/name has OSS = Yes, and that there are open (unassigned) VAT Entries matching those posting group combinations.

Q: Can I re-suggest lines after corrections?
A: Yes. The system asks for confirmation and deletes existing lines before creating new ones. Any VAT Entries previously linked to the deleted lines are unlinked and become eligible again.

Q: Can I add custom export formats?
A: Yes. The NVR OSS Statement XML Format enum is extensible. A developer can add a new enum value and provide a codeunit implementing the NVR OSS Statement XML Export interface.
