# Failed to export into SAP S/4HANA. One-time supplier postings require additional details.

## Error message

```plaintext
One-time supplier postings require additional details. Fill in address fields for this supplier on S/4HANA.
```

## Affected ERP integrations

- SAP S/4HANA®

## Cause

When exporting an expense, you may encounter an error indicating that name and city details are missing for a one-time account posting.

In SAP S/4HANA, a **one-time supplier** (often called a CPD account) is a special vendor profile used for irregular or single-occurrence purchases. Because SAP S/4HANA doesn't store permanent address data for these suppliers, it strictly requires a **Name** and **City** to be provided whenever an expense is posted. If this information is missing during the export from Payhawk, SAP S/4HANA will reject the transaction.

## Solution

The issue usually stems from how the supplier's Master Data or Account Group is configured in SAP S/4HANA.

### SAP S/4HANA Public Cloud Edition

To resolve the issue in SAP S/4HANA Public Cloud Edition:

1. Log into your SAP Fiori launchpad and open the **Manage Supplier Master Data** or **Maintain Business Partner** app.
2. Search for the specific supplier ID associated with this expense.
3. Check the **Account Group**:
  - If this supplier was marked as a **One-Time Supplier** by mistake, update their account group to a regular supplier type.
  - If they must remain a one-time supplier, ensure that the address fields in their central data are properly initialized, or verify that your integration mapping is passing the Payhawk address fields correctly into SAP S/4HANA's one-time invoice fields.

### SAP S/4HANA Private Cloud Edition

To resolve the issue in SAP S/4HANA Private Cloud Edition:

1. Go to transaction code `BP` (Business Partner).
2. Enter the supplier's Business Partner number and switch to the **Supplier** role.
3. Check the **Control** tab to see if the **One-Time Account** checkbox is selected.
  - If this is a regular supplier you use frequently, uncheck this box (you may need to adjust the Account Group via transaction `XK02` or `FK02` depending on your permissions).
  - If it must remain a one-time account, ensure that the required field status for the address (Name and City) allows data to be ingested from external API entries.

### Next steps

Once you have updated the supplier's address details or corrected their account type in SAP S/4HANA, go back to Payhawk and follow the steps:

1. Log in to the [Payhawk Web Portal](https://portal.payhawk.com).
2. Go to **Spend**.
3. Locate the pending expense and click **Review** to re-try the export.
