Trace a product's sales and purchasing in Sage Intacct

**Objective:** For the Akeneo product {sku}, report its sales and purchasing activity in Sage Intacct since a start date {since} (default: the last 90 days), for the Intacct company {company}.

**Step 1: Read the product (akeneo)**

Call `akeneo-get-product` with identifier set to {sku}. Keep product-name, family, brand and enabled. If nothing matches, say so and stop.

**Step 2: Read sales lines (intacct)**

Call `intacct-get-order-entry-document-line` with item-id set to the product identifier and created-date.from set to {since} (and company when given). Keep document-id, customer-name, quantity, price, extended-price and created-date. Total the quantity and extended-price.

**Step 3: Read purchasing lines (intacct)**

Call `intacct-get-purchasing-transaction-line` with item-id set to the product identifier and created-date.from set to {since}. Keep document-id, vendor-name, quantity, price and created-date. Total the quantity and extended-price.

**Step 4: Report**

Product header, then sales totals with the top 5 customers by extended-price, then purchasing totals with the vendors used. Say plainly when there is no sales activity or no purchasing activity in the window.

**Rules & Guidelines:**

* Tools starting akeneo- are on the akeneo server (the product catalog, PIM). Tools starting intacct- are on the intacct server (Sage Intacct, the ERP). Both servers must be connected.
* The join key is the Akeneo product identifier (the SKU) and the Intacct item-id. Compare them exactly first, then trimmed and case-insensitive; report a record that only matches the loose way as a format mismatch, not a match.
* Intacct tools take an optional company; pass {company} when it is given and say which company the answer is for.
* The order entry lines include every document type, so state that the totals mix them unless a line field shows the type.
* This prompt is read-only. Do not call `akeneo-add-product`, `akeneo-update-product`, `akeneo-delete-product`, `akeneo-submit-proposal-product`, or any other akeneo-add-, akeneo-update- or akeneo-delete- tool, and do not call `intacct-create-vendor`, `intacct-update-vendor`, `intacct-create-customer`, `intacct-update-customer`, `intacct-create-order-entry-document`, `intacct-update-order-entry-document`, or any other intacct-create- or intacct-update- tool.

**Validation:**

* If the product has no ERP lines at all, report it as a product with no recorded demand, not an error.
* If the date is not valid, ask for a corrected one and stop.
