Hi Ismael,
I will let OpenERP R&D confirm this, but we don't have plan to extend
the offline capability to all modules, simply because it is impossible
without crippling its usage. Here is why: if you allow offline changes
that get uploaded when you come back online, what do you expect the
software to do when 2 users do something different offline on a single
record? Eg: one user changes an opportunity to qualified stage and
another one changes it to negotiation stage. Worse, what do you expect
when one user goes in one direction of the workflow and another one
goes in another direction. You might want to propose to have a system
of alerts where the second user making the change would be notified,
but can you imagine how unmanageable that would become after spending
several hours working in OpenERP and when you come online the system
tells you that half of what you did cannot be processed.
From what I have seen, the way other software applications like Sage
do it is with a system of locking. A user can lock a record or a list
of records (online) and can work on it offline, and then release the
result of his work when he's done and that he comes back online. This
is very uncomfortable because you end up with tons of records locked
here and there and other people in the company cannot modify what they
need to. Who has worked with Sharepoint and never had to go to the
desk of his colleague to ask him to unlock a file...
The reason why it's possible to go offline with the POS is because it
is only adding records; you are not modifying existing records. So all
you do is push new information to the ERP. Therefore, the offline mode
makes sense for any other application that requires only to push new
information to the ERP.
Forget about an offline mode on, say, quotations. That would be a
nightmare of "update" conflict management between users (salespeople
and their manager typically).
Best,

Hi, Dinil,
I don't know the inner working of Openbravo web POS, could you be more
specific about your plan? Does anybody know if OpenERP has any plans
in respect to implement the offline functionality in a generic way for
any module, or if they plan to maintain the current framework they
used in 6.1 por POS module?
In case they haven't this in their heads, coudn't the community start
such project if enough people were interested in it? I think this is a
very interesting feature for OpenERP.

hi ,
Next week we planned to start working on POS application. The aim
is make the POS similar like web POS of openbravo. I had
some experience on modifying openerp's POS.

Daniel,
here in our company we are asessing the option of extending the
offline functionality of the point_of_sale module, which uses
backbone.js and local storage in the client (big screen
smartphones in our case) to the module we are developing (and to
any generic module by extension).
If you are interested in cooperation of any kind, please contact
me, I think there must be many more companies interested in this
line and we could cooperate.
Regards

Dear community,
At my company, SECURITAS, we are currently using OpenERP
Project modules for field service management.
Also, we would like to equip our field service personnel with
a mobile solution to make it easier for them to manage their
assigned tasks and fill out each intervention's work report.
They already carry laptops with 3G communications, but it
isn't practical enough.
So we're considering to also equip them with a tablet device,
probably 7"-8" Android, and provide a touch screen ready app
to let them do this work on OpenERP.
I had a look at the POS, a I believe that a similar App could
provide a viable solution for our needs.
The offline ability is an important feature for our use-case,
since sometimes work is carried out in places with no GSM or
WIFI connection, like underground locations or remote sites.
My current task is to assess the viability of a satisfactory
OpenERP-based solution for this, and get an idea of what what
kind of costs such a project might involve.
Right now are rather autonomous in 6.0-style module
development, but this project requires some specific technical
knowledge, so we are willing to outsource it.
So, I would appreciate experiences, comments and suggestions.
Thanks and regards,
Daniel Reis
