The allowed maximum number of decimals for the Sum of Invoice line net amount (BT-106) is 2.
Sum of Invoice line net amount (BT-106) is written with more than 2 decimal places.
Round BT-106 to 2 decimals before serialising it. This is a formatting rule, not an arithmetic one - the value itself is usually right, the XML just carries extra digits from a float. Format the amount as a fixed-point decimal string.

Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
