CII-SR-440 for validation X-invoice

[glaejak]

We get the error CII-SR-440 when validating an X-invoice 2.1. This contains two discounts. According to the X-invoice scheme, this is not a problem. However, the EN16931 CII scheme returns the above error.

Since the scheme exams contradict each other, I hope to get help here. Can you tell me if there really is a mistake in the exam or if it is our mistake after all?

This seem to be the rules for BT-147.
And yes, this still applies to the rules 1.3.8

The EN states that the BT-147 , the Item price discount, can only be stated once.
