Here is what I have figured out:
"Manager Owner On Stock" functionality does not work with the default Odoo 8.0 installation.
The Solution comes from the Community: 3 OCA Modules need to be installed
https://github.com/OCA/stock-logistics-workflow/tree/8.0/stock_ownership_availability_rules
https://github.com/OCA/stock-logistics-workflow/tree/8.0/stock_ownership_by_move
https://github.com/OCA/sale-workflow/tree/8.0/sale_owner_stock_sourcing
these Steps provide the functionality
Make a PO, confirm
Take the delivery, add the owner A
transfer (add Lot/Serial Number before clicking Transfer button
The related quant will contain the owner A
then ...
Make a SO
Source it from stock, with owner A
The related quants with the proper owner should be reserved.
(thanks to Joel Grand-Guillaume who provided the workflow on the Community mailing list & Leonardo Pistone for writing these Modules)
have you found anything on this?
Thx for all suggestions. I noticed a lot of 'owner' related commits in github, but answer is opened. I want to understand the operation without the support of the OCA modules.
