I need same advice for how to use "Point of Sale" application in a chain store.

In these issues, I'm trying to find a way to let the stores to access a same odoo pos server from different region.

There are one manager and several cashiers in each store.

First, I want the cashiers can only use the 'points of sales' that linking to the store them work in. However, I couldn't find any references in Odoo User Documentation(https://www.odoo.com/documentation/user/9.0/point_of_sale.html) for configing it. So the cashier can use any 'points of sales' even it not belong to his store.

Second, I want the manager can only select the order data of all cashiers which the same store them with together. But the manager can see the order data of the cashier working in other store.

Are there anyone can give me some advice to avoiding these issues?

Should I just config odoo somewhere? Or I have to modify the source code?

English is not my native language. If any sentence confuse you, just let me know.

Thanks

BTW, there are many third party pos apps in this page, http://www.odoo.com/apps/modules/category/Point of Sale/browse

Are there anyone is designed for chain store?
