separate standard price for variants

[Ferdinand]

for product_template the definition is
        'standard_price': fields.float('Cost Price', required=True, digits_compute=dp.get_precision('Purchase Price'), help="Product's cost for accounting stock valuation. It is the base price for the supplier price."),

nevertheless if variants are used the standard price must be defined for variants

reason
the sale price (list price) is computed based on
        'price_extra': fields.float('Variant Price Extra', digits_compute=dp.get_precision('Sale Price')),
        'price_margin': fields.float('Variant Price Margin', digits_compute=dp.get_precision('Sale Price')),

it is extremely unlikely that a product has an identical standard price and different sales price.

usually different sale prices are caused by different COGS

Hello Dr Ferdinand,

I have checked your issue.But when you use product_variant_multi "extra addons" module.
It will change sale(list) price as well purchase (standard) price after define variant for product. it's working after install it.

Thanks.!!!

thanks for looking into this issue

AFAIK extra addons are not supported by OpenERP

IMHO the modules should be working out of the box correctly

please confirm this as bug, variants can't be used without a fix (which is easy enough )

Further more using the extra_price field yields a bug where the final prices are incorrect.
