Introduction

This document details the proposal of the new account_chart_variant module.

Rationale

As exposed on https://groups.google.com/forum/#!searchin/tryton-dev/account_es/tryton-dev/Z03bdDCb5X8/rBLj-yWwnrIJ in Spain we have two charts of accounts with more than 1000 accounts in common. This module tries to to avoid data duplication, by allowing to create a chart of accounts with diferents accounts.

The module will add a new model to specify chart variants.

Also the module will add the variant field in the create/update chart of accounts wizards, in order to let the user select the desired variant

This model stores the variants of a chart of accounts.

Fields:
- name: Translatable Char
- account: Many2One to account.account with parent set to null (Chart of accounts)

Fields to add :
- variant: not required Many2One to account.chart.variant
Function to modify:
- create_type`: Will not create type if variant is diferent from the variant selected on the wizard. It will create the type if no variant especified on the template.
- update_type`: Will not create type if variant is diferent from the variant selected on the wizard. It will create the type if no variant especified on the template.

Fields to add :
- variant: not required Many2One to account.chart.variant
Function to modify:
- create_account`: Will not create account if variant is diferent from the variant selected on the wizard. It will create the account if no variant especified on the template.
- update_account`: Will not create account if variant is diferent from the variant selected on the wizard. It will create the account if no variant especified on the template.

NOTE: Currently the variant is not introduced in tax's models (as currently not needed), but it can be introducied if anyone needs.
