+The following table describes the validation rules applied when uploading a CSV file.
+
+.. list-table::
+   :header-rows: 1
+   :widths: 20 20 40 20
+
+   * - **Type**
+     - **Field**
+     - **Logic**

+     - Ensure that all required field names are present.
+     - -
+   * - Update
+     - `...NominalAccountNumber` (*n)
+     - If value starts with `xx-`, map `NominalCostCentre` using `dbo.meoCostCentres` and retrieve `NominalAccountNumber` from `dbo.vw_xx-data`.
+     - Ensure the correct nominal code is assigned.
+
+   * - Checks
+     - AccountNumber
+     - Validate against `dbo.meoValidSuppliers`.
+     - Ensure the account exists in the valid suppliers list.
+
+   * - Checks
+     - Source
+     - Should always be `80`.
+     - Reject rows where `Source != 80`.
+

+     - Should always be `4`.
+     - Reject rows where `SYSTraderTranType != 4`.

+     - Set to today’s date (`dd/mm/yyyy`).
+     - Ensure all rows have a consistent transaction date.
+
+   * - Checks

+
+   * - Checks
+     - Combination of `...NominalAccountNumber`, `...NominalCostCentre`, and `...NominalDepartment`
+     - Validate against `dbo.meoValidSageAccounts`.
