## Step 2: Verify the Purchase Order in LN

Before sending the Purchase Order to DocBits, verify that the **Delivery Number** is correctly assigned in **LN**. Check the **Purchase Order** details in **LN** to ensure that it is complete and accurate. If the **Delivery Number** is missing or incorrect, this could be the cause of the export error.

If the **Purchase Order** appears correct and contains the necessary details, you can proceed to the next step.

## **Step 3: Open DocBits Settings**

1. Open **DocBits** and go to the **Settings** section.
2. Navigate to **Document Processing**.
3. Select **Export**.
4. In the **Export** section, click on the **three dots** icon next to the export that is not working and select **Edit**.
5. In the **Edit Export Settings** menu, click **Download the LN-Mapping** file.

## **Step 3: Edit LN-Mapping File**

1. Open the downloaded **LN-Mapping** file.
2. Search for the field **IRF\_ReceiptLine**.
   * If the field **IRF\_ReceiptLine** is present and set to **nothing** (empty), update it to **TF\_delivery\_line**.
   * If the field **IRF\_ReceiptLine** is **not present**, add it to the file and set its value to **TF\_delivery\_line**.
3. For the field **InvoiceReceiptFields,** add **ReceiptLine** to the values.

It should look like the following:

1. Go back to the **Export** section in DocBits where you previously downloaded the **LN-Mapping** file.
2. Upload the edited **LN-Mapping** file with the new updates.

## Step 5: Retry the Export

After confirming that the **Purchase Order** has a **Delivery Number** and ensuring the **Export file is correct**, follow these steps to retry the export:

1. **Return to the Dashboard:**
   * Go back to the dashboard and find the document with the export error.
2. **Retry the Export Process:**
   * Click on the document with the export error.
   * If the **Purchase Order** has a valid **Delivery Number** and the **Export file** is correct, proceed to retry the export.
3. **Check the Export Result:**
   * After retrying, check the export process again to see if the issue has been resolved and the document no longer shows as an export error.
   * If the export is successful, the issue should be resolved.
4. **Further Investigation (if the problem persists):**
   * If the issue persists after retrying the export, contact support for further investigation into possible configuration or system issues.
