XRechnung 2.0.2: UBL validation rule changes

For an endpoint identifier (cbc:EndpointID or ram:URIID) that has a schemeID and the invoice declares itself as an XRechnung extension, the schemeID must be exactly one of the codes from the CEF EAS code list accepted by the rule, with no spaces inside the value. The test fails if the schemeID is empty or whitespace-only, contains an internal space, or is not in the allowed code list.

Set the schemeID attribute to a valid CEF EAS code from the rule's list, such as "0088" or "0208". Ensure the value is not empty and does not contain spaces. If the current scheme identifier is not in the list, map it to the appropriate CEF EAS code.

The rule requires cbc:TaxCurrencyCode (UBL) or ram:TaxCurrencyCode (CII) to hold an ISO 4217 alpha-3 currency code from the list accepted by BR-CL-05. It passes only when the normalized value is exactly one of the 178 listed codes, for example EUR, USD, or GBP. A document fails if the element is empty, contains only whitespace, has an internal space, or uses a code not on that list.

Put a valid ISO 4217 alpha-3 currency code in the tax currency field, such as EUR, USD, or GBP. Ensure the value has no internal spaces (surrounding whitespace is ignored by the rule) and is not empty or only whitespace. Check that the code is present in the BR-CL-05 list; if the current code is something else, replace it with the correct three-letter ISO 4217 code.

The rule requires the invoice currency code to be a valid ISO 4217 alpha-3 currency code. It checks that the code contains no spaces and appears in the rule's list of accepted currency codes. A document fails if cbc:DocumentCurrencyCode (UBL) or ram:InvoiceCurrencyCode (CII) is empty, contains whitespace, or is not one of the listed codes.

Set the currency code element to a three-letter ISO 4217 code from the list allowed by the rule, for example EUR, USD, or GBP. In UBL use cbc:DocumentCurrencyCode; in CII use ram:InvoiceCurrencyCode. Ensure the value contains no spaces.

The rule requires that the @currencyID attribute on amount elements (UBL) or on ram:TaxTotalAmount (CII) contains an ISO 4217 alpha-3 currency code from the list accepted by the rule, and that the code contains no spaces. Because the severity is fatal, an invoice that does not satisfy this condition is rejected with message [BR-CL-03]-currencyID MUST be coded using ISO code list 4217 alpha-3.

Set the currencyID attribute to a valid three-letter ISO 4217 alpha-3 code that appears in the rule's list, for example EUR or USD. Ensure the value is not empty and contains no spaces. In UBL this applies to amount elements such as cbc:TaxAmount; in CII it applies to ram:TaxTotalAmount[@currencyID]. If the current value is not a valid code, correct it in the source system.

For each cac:AdditionalDocumentReference, the rule allows only three situations: cbc:DocumentTypeCode equals 130; or, on a CreditNote, cbc:DocumentTypeCode equals 50; or neither cbc:ID/@schemeID nor cbc:DocumentTypeCode is present. If a reference has a cbc:ID/@schemeID without one of the allowed document type codes, or has a cbc:DocumentTypeCode other than 130/50 (with the credit note condition), the document is rejected. This is a fatal rule, so a violation fails validation.

Check each cac:AdditionalDocumentReference. If it represents an invoiced object, set cbc:DocumentTypeCode to 130 (or 50 if the document is a CreditNote). If it does not, remove both cbc:ID/@schemeID and cbc:DocumentTypeCode from that reference. Do not leave cbc:DocumentTypeCode with an unlisted value, and do not include cbc:ID/@schemeID without the required document type code.
