I'm using Odoo 11 with multi company 

i have three company  A => the parent, B and C as child.

every company have chart of account and  stock location and Warehouses ..etc

with Common Contact Book and Common Product Catalog

i'm created POS for every company ( POS Setting https://ibb.co/XDPXBjc )

and created user for company ( https://ibb.co/dkPc44b )

the user can open POS and create orders but when closing and validate git error message ( Cannot create moves for different companies. )

what's wrong ?
