How to fix BR-DEX-15
This CII file might use the concept of Sub Invoice Lines. However XRechnung does not support this.
XRechnung rule from the KoSIT XRechnung 3.0 schematron (German CIUS of EN 16931). It applies only to invoices whose specification identifier (BT-24) is XRechnung. Such files are checked against EN 16931 and the KoSIT XRechnung rules instead of the full Peppol BIS rule set. Check your file with the XRechnung validator.
What this rule checks
In a CII file with the XRechnung extension identifier, ram:ParentLineID suggests sub invoice lines. XRechnung only supports sub invoice lines in UBL, so the hierarchy will not be understood by receivers.
How to fix it
Remove ram:ParentLineID from ram:AssociatedDocumentLineDocument and send flat lines, or switch to UBL if you need sub invoice lines.
