Add BE Peppol localization with Enterprise No. support #6268

Copilot · 2026-01-23T16:48:40Z

Belgium PEPPOL requires two deviations from W1: VAT registration numbers must use FormatEnterpriseNo for BE companies, and document validation must accept "Enterprise No." as alternative to GLN/VAT Registration No.

Changes

New App: `src/Apps/BE/Peppol`

PEPPOL Party Info Provider Implementation (PEPPOL30 BE)

Overrides all methods that internally call FormatVATRegistrationNo to use BE-specific logic
For BE countries, applies FormatEnterpriseNo which prepends ISO code only to numeric-only enterprise numbers

if IsBelgiumCountry(CountryCode) then
    VATRegistrationNo := FormatEnterpriseNo(VATRegistrationNo, CountryCode)

Validation Implementation (PEPPOL30 BE Sales Validation)

Extends company/customer validation to include Enterprise No.:

if CompanyInfo.GLN + CompanyInfo."VAT Registration No." + GetEnterpriseNo(CompanyInfo) = '' then
    Error(MissingCompInfGLNOrVATRegNoOrEnterpNoErr, ...);

Integration events: OnCheckSalesDocumentOnBeforeCheckCompanyVATRegNo, OnCheckSalesDocumentOnBeforeCheckCustomerVATRegNo

Enum Extension (PEPPOL 3.0 Format BE)

Registers PEPPOL 3.0 - BE Sales and PEPPOL 3.0 - BE Service with BE implementations

PR #6268 implements BE-specific PEPPOL export (Enterprise No. formatting/validation) but only for Sales documents. Service documents would fall through to W1 implementation, missing Belgium Enterprise No. support entirely. ## Changes - **Added** `PEPPOL30 BE Service Validation` codeunit (37312) - delegates to BE Sales validation via service→sales conversion (mirrors W1 pattern) - **Extended** `PEPPOL 3.0 Format BE` enum with `"PEPPOL 3.0 - BE Service"` value (37311) implementing BE Party Info Provider + BE Service Validation - **Updated** subscriber to set both `"PEPPOL 3.0 Sales Format"` and `"PEPPOL 3.0 Service Format"` on setup insert ## Format Selection Flow ```al // Export codeunits read setup and dispatch to format implementation Exp. Sales Inv. PEPPOL30 → Setup."PEPPOL 3.0 Sales Format" → PEPPOL30 BE → FormatEnterpriseNo ✓ Exp. Serv.Inv. PEPPOL30 → Setup."PEPPOL 3.0 Service Format" → PEPPOL30 BE → FormatEnterpriseNo ✓ (was: PEPPOL30 W1 → No Enterprise No.) ``` Both document types now apply BE-specific: - `FormatEnterpriseNo`: Prepends ISO code to numeric-only enterprise numbers - Validation: Accepts GLN **OR** VAT Reg No. **OR** Enterprise No. (W1 only accepts first two)   <details> <summary>Original prompt</summary> > Pull Request: #6268 > > Please analyse how/if this app correctly overrides behaviour of the W1 app when user executes the export of sales or services docs. > </details>  --- 💡 You can make Copilot smarter by setting up custom instructions, customizing its development environment and configuring Model Context Protocol (MCP) servers.

Too much, you do not need so many objects. Lower it down to 37350

Do you need to set InternalsVisibleTo from W1 peppol app to BE one?
