[Lorenzo Battistini]

This module handles parallel accounting entries based on different currencies.
It is useful for companies who have to manage accounting with more than one currency at the same time. For instance, companies who have to produce balances on different currencies.

In order to use the module, you have to define one company for each parallel chart of accounts. Then you have to map parallel accounts and parallel journals through the related forms.

A 'Parallel Account Mapping' wizard is provided. It is intended to be run when the same chart of account is used for the parallel companies. It allows to automatically map the 'master' account to 'parallel' accounts, based on account code.

When posting new journal entries, the system checks the configured parallel accounts and automatically generates the parallel entries.
For each user, it is possible to configure a 'parallel user' (that should be associated to a dummy parent company), used to carry out the parallel registrations. This allows to keep the companies separate, so that users of the master company don't see secondary company data (e.g. currencies and journals) but the system uses his parallel user in order to perform the parallel registrations

Hi Lorenzzo,

Sorry for the question : this looks very interesting but I cannot find any cases/example in real situation where this could be a must have...
I mean, why would you duplicate the entire accounting books of the company instead of simply do a report or a view which convert account balances ?
Any legal reason ? unless a segregation of duties issue maybe ?

Thanks

Frederic

Hi Lorenzo,

We have same question, we frequently use Consolidated accounts to build consolidation reports, some specific or generical reason or accounting Good practice to support the development?

For sure i had some times this idea in my mind because when you have some customers you think in several options to solve the problem, but i never developed because Consolidated acounts works for me.

Regards, and Kudos for you contribution

Hi Frederic and Nhomar,

simply converting balances can be insufficient if you have to consider
historical rates.

Just found a recent publication
<http://www.altenburger.ch/uploads/tx_altenburger/mc_2013_Revisione_del_diritto_contabile_svizzero.pdf>
(Italian) about Swiss accounting law.

The interesting part:

"To facilitate the international companies, moreover, the accounts can
be held in one of the national languages ​​(German, French, Italian)
and, in addition to the CHF, other currencies are accepted - crucial for
the company activities - such as Euro or USD, with an indication,
however, of the values ​​in CHF too"

[Stefan Rijnhart (Opener) (stefan-opener)]

This has been the oldest proposal on the community projects for some time now, maybe because of the relatively rare business case, and the large amount of code impacting the core of the accounting system. So I'll have ago. I think I can understand the particular business case of this module, and the code does look good. Tests are provided too, so I think this should be fine.

It would be nice to know whether this module has already been used in production by now?

One nit:

l.174..185 + l.535..536 is a bit tiresome. Can you make this a list comprehension or at least iterate over a list of fields?

Thanks Lorenzo.

Can you please run autopep8 on your module ?

Hello Stefan.

The module has been used in production from this winter.

Unfortunately, we could not verify deeply the data accuracy yet. We will
probably do it at the end the year.

That's quite alright by me for now. I think this proposal has been waiting long enough.
