Title
VATEX ExemptionReasonCode not written to Header VAT Breakdown (BR-IC-10 violation)

Environment

• ERPNext 15.x
• eu_einvoice 15.x
• Hosted on Frappe Cloud

Scenario

• Intra-community supply (DE → SK)
• VAT Category Code: K
• VAT Rate: 0%
• VATEX-EU-IC mapped via Code List (Applies to: Tax Category, Account, Sales Taxes and Charges Template)

Observed Behaviour

• VATEX-EU-IC is correctly written at line level:
  ram:SpecifiedLineTradeSettlement
  ram:ApplicableTradeTax
  ram:TypeCodeVAT</ram:TypeCode>
  ram:CategoryCodeK</ram:CategoryCode>
  ram:ExemptionReasonCodeVATEX-EU-IC</ram:ExemptionReasonCode>
  ram:RateApplicablePercent0</ram:RateApplicablePercent>
  </ram:ApplicableTradeTax>
  </ram:SpecifiedLineTradeSettlement>

• However, the same exemption reason is not written in the VAT Breakdown at header level:
  ram:ApplicableHeaderTradeSettlement
  ram:ApplicableTradeTax
  ram:CalculatedAmount0.0</ram:CalculatedAmount>
  ram:TypeCodeVAT</ram:TypeCode>
  ram:BasisAmount20.0</ram:BasisAmount>
  ram:CategoryCodeK</ram:CategoryCode>
  ram:RateApplicablePercent0</ram:RateApplicablePercent>
  </ram:ApplicableTradeTax>
  </ram:ApplicableHeaderTradeSettlement>

The header VAT Breakdown contains:

• CategoryCode = K
• RateApplicablePercent = 0
• but no ExemptionReasonCode and no ExemptionReason text

Result
Peppol validation fails with:
[BR-IC-10] – A VAT Breakdown (BG-23) with VAT Category Code (BT-118) "Intra-community supply" shall have a VAT exemption reason code (BT-121), meaning "Intra-community supply" or the VAT exemption reason text (BT-120) "Intra-community supply" (or the equivalent standard text in another language).

Expected Behaviour
If VATEX-EU-IC is determined for VAT Category K, it should also be written in the corresponding Header VAT Breakdown block (BT-121), or alternatively the exemption reason text (BT-120) should be populated.

Do you have any zero rows in your Taxes and Charges table? If so, try removing them.

@barredterra : There is only one row in the "Sales Taxes and Charges" table.

Type: On Net Total
Account Head: 8125 – Steuerfreie innergemeinschaftliche Lieferungen §4 Nr.1b UStG
Rate: 0%

No additional zero rows exist.

Can you try to assign a "tax_category" the "VATEX-EU-IC" (possibly create a tax category before) and leave the field "taxes_and_charges" empty (with your one row 8125 left and/or removed)?
