2. Search for the field **IRF\_PackingSlip**.
   * If the field **IRF\_PackingSlip** is present and set to **nothing** (empty), update it to **TF\_packing\_slip**.
   * If the field **IRF\_PackingSlip** is **not present**, add it to the file and set its value to **TF\_packing\_slip**.
3. For the field **InvoiceReceiptFields** add **PackingSlip** to the values.
