Official rule text

[BR-DE-30] If "DIRECT DEBIT" BG-19 is present, "Bank assigned creditor identifier" BT-90 must be transmitted.

Official text (German): Wenn "DIRECT DEBIT" BG-19 vorhanden ist, dann muss "Bank assigned creditor identifier" BT-90 übermittelt werden.

Why this error occurs

This rule only applies when another field has a certain value (for example a payment means code or an invoice type). Your file triggers the condition but does not provide the data that then becomes mandatory, or provides data that is then forbidden.

How to fix it

Either change the triggering value so the condition no longer applies, or add/remove the dependent elements as the rule text describes. Check the condition in the XPath test above to see exactly which value triggers it.
