Infor LN (Baan) and e-Invoicing: Integration, Top 10 Rejection Causes, and Compliance Hub 2026

The e-Invoicing Context 2024-2026

Since July 2024, electronic invoicing (XML UBL 2.1 according to CIUS-RO) has been mandatory for all B2B transactions in Romania. ANAF automatically rejects any invoice that fails syntactic (XSD) and semantic (business rules) validations.

For companies processing 1,000-5,000 invoices/month, a rejection rate of 3-9% (typical for an ERP without a semantic layer) means 40-120 invoices/month to be manually corrected → hidden cost of €30k-100k/year.

Integrating Infor LN (Baan) with e-Invoicing

Infor LN (Baan) utilizes an e-invoicing connector via a local partner add-on that:

1. Generates XML UBL 2.1 from the Infor LN (Baan) invoice

2. Validates the XSD schema (syntactic)

3. Sends to the tax authority SPV (API + token authentication)

4. Receives the response (accepted / rejected + reason)

5. Attaches the upload ID to the Infor LN (Baan) invoice

Time-to-deploy: 2-6 weeks. Cost: €15k-60k setup + €5k-15k/year maintenance.

Top 10 ANAF Rejection Causes (Across All ERPs)

|---|-------|------------------|--------|

| 1 | Invalid Partner VAT ID (VIES) | 18% | blocked invoice, manual follow-up |

| 2 | Wrong / Missing CPV code | 14% | semantic rejection, recoding |

| 3 | Inconsistent VAT line-to-document | 12% | recalculation + resubmission |

| 4 | Partner without active fiscal account | 10% | registration check + master data update |

| 5 | Invalid IBAN (MOD-97) | 8% | IBAN correction + resubmission |

| 6 | Non-standard Unit of Measure (UM) | 7% | internal UM → tax authority code mapping |

| 7 | Missing Central Bank exchange rate | 6% | rate fetch + local currency recalculation |

| 8 | Item missing barcode/GTIN | 5% | item master update |

| 9 | Incomplete partner address | 4% | postcode + region validation |

| 10 | Wrong document type | 3% | mapping GRN/Proforma/Invoice |

Why Native Infor LN (Baan) Doesn't Catch Everything

The native Infor LN (Baan) connector validates XSD (syntactic) and sends the file. However, most rejections are semantic (CIUS-RO business rules) — which require:

VIES live check (API ec.europa.eu/taxation_customs/vies)

Fiscal status check (active / inactive company)

CPV taxonomy matcher (15,000+ CPV codes)

VAT matrix (19% / 9% / 5% / 0% rates per transaction type)

IBAN MOD-97 validator (mathematical formula)

Central Bank exchange rate fetch automatic for the invoice date

Azuvio Compliance Hub — 40+ Semantic CIUS-RO Rules

The Compliance Hub runs before submission to the tax authority as a pre-validation layer:

40+ semantic rules (all top 10 causes + 30 edge-cases)

Auto-fix for 18 categories (IBAN, UM, exchange rates, address format)

Alerts to the accountant for issues that cannot be auto-fixed

Dashboard with real-time rejection rates

Infor LN (Baan) Integration: read invoice → validate → write status back

ROI of Compliance Hub for Infor LN (Baan)

For a company with 2,500 invoices/month (average for regional distribution):

Rejections before: 3-9% → 75-225 invoices/month

Rejections after Compliance Hub: <0.5% → <13 invoices/month

Accountant time recovered: 40-80h/month → savings of €24k-48k/year

Compliance Hub cost: ~€18k-32k/year subscription

Year 1 ROI: 2-3x

Verdict

Infor LN (Baan) + a native e-invoicing connector covers the syntactic requirements. For semantic accuracy (90% of actual rejections), you need the Azuvio Compliance Hub — without modifying Infor LN (Baan) and without upgrade risks.
