Keeping up to date with the latest EHF version

The EHF format is updated from time to time, often due to changes with the PEPPOL standards or due to Norwegian regulations.

For a Norwegian supplier, it’s important to always keep up to date with the latest standards, no matter what sender format their system produces initially. If the receiver is set up for EHF, Basware will make sure to convert the format accordingly based on the contents of the initial document. And prior to sending the documents towards PEPPOL, all operators are obligated to make sure they are valid and in line with the current standards. If the data within the initial document (whether it be EHF of another format) doesn’t correspond to the latest EHF standards, they will fail in validation after conversion, thus not being delivered as intended.

Please note that the sender alone is responsible of keeping their initial format compatible with the standards of the receiver (EHF in this case).


In EHF 2.0.13 (20.02.2018), the following rule was added:


“[NONAT-T10-R033]-Base quantity must be a positive value higher than zero.”

In practice, this means that the unit price for an item must be based on a positive number of items. Normally you’d want 1 as the base quantity here, but exceptions are allowed. If this is set to a negative value however, no matter the format used, it will not be compatible with EHF rules. It would therefore fail in validation and not be delivered if the recipient is set up to receive EHF.
