# BI View Editor

BI View Editor is a tool integrated in Odoo that allows users define and execute their own reports without the need to code.

Purpose:

- The BI View Editor is used to create reports not already contained in the standard Odoo, combining data from existing sources.
- It has been designed to be used by users with little or no knowledge of the technical architecture of Odoo. Users visually link business objects and select the fields to visualize.
- The BI View Editor offers users different types of representations, including tree, graph, pivot views.

# Installation

In the Odoo configuration file add `bi_view_editor` in the list `server_wide_modules`:

    [options]
    (...)
    server_wide_modules = web,bi_view_editor
    (...)

Alternatively specify `--load=bi_view_editor` when starting Odoo by command line.

Optionally it is possible to enable the view of the ER Diagram. For this you need to install Graphviz, an open source graph visualization software:

    ``sudo apt-get install graphviz``

# Usage

To graphically design your analysis data-set:

- From the Dashboards menu, select “Custom BI Views”
- Browse trough the business objects in the “Query Builder” tab
- Pick the interesting fields (Drag & Drop)
- For each selected field, right-click on the Options column and select whether it’s a row, column or measure; if you want to remove the field from the list view, unflag the checkbox ´List´ in the Options column
- Save and click “Generate BI View”
- Click “Open BI View” to view the result

To access the created BI View with a dedicated menu:

- If module Dashboard (board) is installed, the standard “Add to My Dashboard” functionality would be available
- Click “Create a menu” to create a new menu item directly linked to your new BI view (this feature is available in developer mode); when the BI view is reset back to draft this menu will be removed, and you will need to re-create the menu entry.

A more advanced UI is also available under the “Details” tab. It provides extra possibilities for more advanced users, like to use LEFT JOIN instead of the default INNER JOIN.

It also possible to improve the IDs generation for new views by adding an Over Condition in the “SQL” tab, see https://www.postgresql.org/docs/current/sql-expressions.html#SYNTAX-WINDOW-FUNCTIONS for further details. For instance, an ORDER BY clause helps preventing unreliable behavior when filtering the generated views.

# Known issues / Roadmap

- Non-stored fields and many2many fields are not supported.
- Provide a tutorial (eg. a working example of usage).
- Find better ways to extend the _auto_init() without override.
- Possibly avoid the monkey patches.
- Data the user has no access to (e.g. in a multi company situation) can be viewed by making a view. Would be nice if models available to select when creating a view are limited to the ones that have intersecting groups.

# Bug Tracker

Bugs are tracked on GitHub Issues. In case of trouble, please check there if your issue has already been reported. If you spotted it first, help us smashing it by providing a detailed and welcomed feedback.
