In case of a move where source location = destination location, the result of
SUM(quantity) would be 0 and ending up with a division by zero.
Closes#12247Closes#12423
The view yields one line per stock move, with a price/unit on each line.
It doesn't make sense to sum price/units, the avg will be only meaningful when
grouping per product but it's correct in the default state.
Closes#11309
The stock history doesn't take into account internal moves. For example,
in the following situation:
- Receive 1000 products to Internal Warehouse 1
- Move these 1000 products to Internal Warehouse 2
The 1000 products are still recorded on the Internal Warehouse 1.

The revision 29bd622521
aimed to improve the performance by changing
the view index, to use a BIGINT instead of a text.
It was assumed that the index used
(`stock_move.id`) could not appear
multiple times with the JOINs and
group bys defined.
This was in fact possible, if a
stock move is associated to
several quants with different costs,
because of the JOIN on the many2many table
`stock_quant_move_rel`
linking quants to moves,
and the GROUP BY
`price_unit_on_quant`
that caused the different moves/quants association
not to be merged within one unique line
if the costs on the quants are different.
Instead of the group by, we now aggregate the quants
costs, using the weighted average, so the index
used can be unique, as expected.
From now, the inventory value per line in
this report view can therefore
be different than what can be found on the quants,
but this report view is based on the stock moves
rather than the stock quants, and this is therefore accepted.
In other words, the inventory value is computed for the stock move
rather than for the stock quant.
opw-658903
When performing a stock valuation at date,
the stock valuation total wasn't equal
to the sum of each line of the report.
This is because the domain forcing the
date wasn't passed to the `search` call
when no group by was applied.
Indeed, when calling
`read_group` with a group by, the lines in the results
contains the domain used for each line, but when
there is no group by applied, this is not the case, the domain
is not included in the line dict returned by `read_group`.
In such a case, therefore, we must use the domain that was passed to
the `read_group` call.
opw-667761
Using BIGINT id instead of Text
- This doesn't change the behavior, just the variable type,
while being much more efficient.
Using `UNION ALL` instead of simple `UNION`
- This doesn't change the behavior either,
as the ids of each sub select cannot collide
Closes#9197
opw-650598
The function "open_table" is not called when triggering the action
window "Current Inventory Valuation". Then the 'history_date' is not
set in the context.
opw:649168
The valuation wizard is based on stock moves and currently only takes into
account the moves which have different companies in source vs destination
locations.
This is a problem because all user-created locations have a default company set
to the user's company, even the "virtual" ones. For example in the demo dataset
visible on runbot, some supplier locations have a company set and some don't.
So we have to make sure to include every move coming from/going to
outside locations based on the locations's type too.
Closes#7530
This is related to rev. 55b7f15ee2
Prevent crash when there is no line to display
in the stock valuation report
Reporting > Warehouse > Stock Valuation.
Like when there is not yet any data, or the filter gives no result
opw-643748
Basically, computation of the `inventory_value` is now done
in batch instead of one by one.
In a real use case, the computation of the stock valuation
passed from 20+ minutes to less than a minute.
This revision contains an unusual SQL request:
`SELECT DISTINCT ON`
Basically, it returns the most recent line of table
product_price_history for each tuple
`(product_template_id, company_id)`
which is actually what we want, with good performances.
See postgresql doc for more information:
http://www.postgresql.org/docs/9.0/static/sql-select.html#SQL-DISTINCT
opw-641154
Without this fix, the 'Total' line of the pivot view does not display any inventory value, because there is no __domain as we are not asking the inventory value for any specific product.
