The VAT Posting Setup does not exist. ## Error message ```plaintext Failed to export into MS Business Central. The VAT Posting Setup does not exist. ``` ## Affected ERP integrations - MS Business Central ## Cause This error occurs when the combination of **VAT Business Posting Group**, from the vendor, and **VAT Product Posting Group**, from the G/L account, used in the expense does not exist in the VAT Posting Setup table in MS Business Central. The system attempts to use: - **VAT Business Posting Group** - retrieved from the vendor record associated with the expense. - **VAT Product Posting Group** - retrieved from the G/L account mapped to the expense category. If this specific combination is not configured in MS Business Central's VAT Posting Setup, the export will fail. > [!TIP] > This logic applies to both Purchase Invoices and Journal Lines. For Journal Lines, the journal or batch must have the **Copy VAT Setup to Journal Lines** setting enabled for VAT posting groups to be applied correctly. ![General journal batches with highlighted options for VAT setup and journal lines.](https://cdn.payhawk.com/Adm%3AIntegrations%3AError%20messages/msbc_vat_3.png) ## Solution To resolve this issue: 1. Identify the VAT Posting Groups used: 1. Log in to your MS Business Central account. 2. Navigate to the **Vendor** record associated with the expense and note the **VAT Business Posting Group** value. 3. Navigate to the **G/L Account** mapped to the expense category in Payhawk and note the **VAT Product Posting Group** value. 2. Add the combination to VAT Posting Setup: 1. In MS Business Central, navigate to **VAT Posting Setup**. 2. Check if a row exists with the identified **VAT Business Posting Group** and **VAT Product Posting Group** combination. 3. If the combination does not exist, create a new entry with those values. For example, if the vendor has VAT Business Posting Group = EXPORT and the G/L account has VAT Product Posting Group = REDUCED, you must create a row in the VAT Posting Setup table with these exact values. ![Account card showing sale details and vendor information for Boombastic LTD.](https://cdn.payhawk.com/Adm%3AIntegrations%3AError%20messages/msbc_vat_error_messages.jpg) 3. Save and re-export: 1. Save the new VAT Posting Setup entry. 2. Return to the Payhawk Web Portal and try to export the expense again.
