Open *Dashboards → Cooperative* in the Odoo backend. Four dashboards
are published:

The workbook content (titles, KPI labels, table headers, scorecard
descriptions) is available in **English (source) and Spanish** out of
the box. Users with ``lang = es_ES`` will see all in-cell texts in
Spanish; the rest of the locales can be added by translating the
``i18n/spreadsheet_dashboard_pos_cooperative.pot`` template.

Note: the dashboard names shown in the *Dashboards* menu sidebar
(*POS Overview*, *POS Members*, *POS Categories*, *POS Sales by
Time*) are not translatable because ``spreadsheet.dashboard.name`` is
not declared as a translatable field in Odoo core.

POS Overview
============

Headline KPIs and monthly evolution for the whole store.

* **Sales (€)** — sum of ``price_total`` over orders in the period.
* **Orders** — count of distinct ``order_id``.
* **Average ticket (€)** — ``Sales / Orders``.
* **Gross margin (€)** — sum of ``margin``.
* A line chart with monthly sales evolution.

POS Members
===========

Detailed comparison between cooperative members and non-members. For
each group the dashboard shows:

* Sales (€), Orders, Average ticket (€), UPT, Distinct buyers, and
  (members only) Frequency.
* Monthly evolution chart with one line per group.
* TOP 50 buying members (ranked by sales), with sales, orders, units,
  average ticket and UPT.

POS Categories
==============

Members contribution KPIs and the top product breakdowns.

* **Members sales (€)** — sales from orders where the customer was a
  cooperative member at the order date.
* **Purchase share** — ``members sales / total sales``.
* **Members penetration** — ``distinct members buyers / distinct total
  buyers`` (see "Metric definitions" below for the caveat).
* TOP 10 product families (root categories) with sales, orders, share %.
* TOP 10 product subfamilies (parent categories) with the same columns.
* TOP 10 products with sales, units, share %.

POS Sales by Time
=================

* Line chart of sales by ISO day of the week (1 = Monday, 7 = Sunday).
* Line chart of sales by hour of the day (0..23).

Global filters
==============

Every dashboard ships a ``Period`` date filter. Members, Categories
and Sales by Time also ship ``Product Category``, ``Product`` and
(Members only) ``Member`` relation filters. Each filter is wired to
every pivot and chart on the dashboard, so changing one selection
updates the whole view.

* **Period** — year picker plus a month dropdown
  (January..December). Pick a year only to look at the full year
  (e.g. *2026*, *2025*), or add a month to narrow the range (e.g.
  *March 2026*). Defaults to the current month.
* **Product Category** — relation picker over ``product.category``.
  Choose one or more categories to restrict every metric to products
  of those categories. Empty = no restriction.
* **Product** — relation picker over ``product.product``. Useful to
  audit a specific reference.
* **Member** — relation picker over ``res.partner``. Available only
  on the Members dashboard; restricts the comparison and the TOP 50
  to the selected partners.

Note: the o-spreadsheet date filter in Odoo 16 only accepts a single
``rangeType`` per filter (year, quarter or month). We chose ``month``
because it is the finest granularity the customer requested; for
year-only views, just pick a year and leave the month dropdown
unset. Rolling ranges (*Last 30 / 90 / 180 days*) and quarter
selection (*Q1..Q4*) are not available on the spreadsheet filters;
both are handled in ``pos_dashboard_cooperative`` through the
standard search view on *Point of Sale → Reporting → Cooperative
Dashboards*, which exposes the usual Odoo date filters.

Metric definitions
==================

The BI brief from the customer left several KPIs without a precise
formulation. The dashboards use the following standard retail
definitions; revise them in the JSON if your cooperative prefers a
different convention.

* **UPT** (Units per Ticket) = ``total units sold / number of
  orders``. ``product_qty`` summed and divided by distinct
  ``order_id``.
* **Frequency** = ``number of orders / number of distinct buyers``.
  Measures how many tickets the average member buyer made in the
  period.
* **Average ticket (€)** = ``total sales / number of orders``. POS has
  no separate "average ticket value", so this metric matches the
  "Ticket medio" and "Valor medio del ticket" rows in the BI brief.
* **Purchase share %** = ``members sales / total sales``. Share of
  total revenue contributed by member-driven orders.
* **Members penetration %** = ``distinct member buyers / distinct
  total buyers`` *in the selected period*. Note: a stricter definition
  would be ``distinct member buyers / total members in the
  cooperative`` (regardless of whether they bought). That denominator
  is not exposed by ``report.pos.order``; a future iteration may add a
  separate KPI sourced from ``share.line``.
* **Sales concentration** (not yet rendered) would be the share of
  sales captured by the top X% of buying members, typically X = 20.
  Easy to add later from the same ``Top buyers`` pivot.

Iterating on the layouts
========================

Each dashboard is a ``data/files/*.json`` file shipped as a base64
binary on a ``spreadsheet.dashboard`` record. They are intentionally
small and hand-authored to be diff-friendly.

To redesign one of them visually:

1. Install ``spreadsheet_oca`` (from OCA's ``spreadsheet`` repository)
   on top of this module. It provides full o-spreadsheet editing in
   the backend, including saving back to ``spreadsheet.dashboard``.
2. Open the dashboard in *Dashboards → Cooperative*.
3. Edit pivots, charts, styles and global filters from the
   o-spreadsheet UI. The data sources are pre-wired against
   ``report.pos.order`` and consume the dimensions exposed by
   ``pos_dashboard_cooperative``:

   * ``is_member_at_date`` (boolean) — cooperative member flag at the
     order date.
   * ``categ_root_id`` / ``categ_parent_id`` — product family /
     subfamily.
   * ``hour_of_day`` / ``day_of_week`` — time distributions.

4. Export the workbook to JSON.
5. Replace the matching ``data/files/<name>.json`` and reinstall (or
   upgrade) the module.

Reference: the same workflow is used by Odoo core's
``spreadsheet_dashboard_sale``, ``spreadsheet_dashboard_purchase`` and
similar modules.
