Find where a BigCommerce order landed in Dynamics GP

**Objective:** Trace BigCommerce order `{order-id}` into Dynamics GP and report whether the sales document exists and agrees with the order.

**Step 1: Read the order**

Call `bigcommerce-get-order` (bigcommerce server) with `id` set to `{order-id}`. If nothing matches, report that and stop. Keep `customer-id`, `total-including-tax`, `total-tax`, `date-created`, `billing-email` and `status`.

**Step 2: Read the order lines**

Call `bigcommerce-get-order-product` (bigcommerce server) with `order-id` set to `{order-id}`. Keep `sku`, `quantity` and `price-excluding-tax` per line.

**Step 3: Find the sales document in Dynamics GP**

The convention is that the GP customer PO number holds the BigCommerce order id. Call `dynamics-gp-get-rm-sales-trx` (dynamics-gp server) with `customer-po-number` set to `{order-id}`. If nothing comes back, report the order as present in BigCommerce and absent from Dynamics GP and stop. If several come back, list them and use the one whose `document-amount` is closest to the order total. Keep `sop-number`, `sop-type`, `customer-id`, `document-amount`, `tax-amount` and `posting-status`.

**Step 4: Read the GP lines**

Call `dynamics-gp-get-rm-sales-line-item` (dynamics-gp server) with `sop-number` and `sop-type` from Step 3. Keep `item-number`, `quantity` and `unit-price`.

**Step 5: Report**

Header comparison (total, tax) with the difference. Line comparison matching BigCommerce `sku` to GP `item-number`: lines only in BigCommerce, lines only in GP, and lines whose quantity or price differs. End with one verdict: In step, Differs, or Not in Dynamics GP.

**Rules & Guidelines:**

* `bigcommerce-*` tools run on the bigcommerce server and `dynamics-gp-*` tools on the dynamics-gp server. Both servers must be connected.
* Where a GP tool takes `company`, pass `{gp-company}` when it is given; if it is empty, omit `company`.
* This prompt is read-only. Never call any `bigcommerce-*-add`, `-update` or `-delete` tool, and never call any `dynamics-gp-*-add`, `-update` or `-note` tool.

**Validation:**

* If there is no PO number match, say the order may have been keyed with a different reference.
* Amounts within 0.01 are equal.
