Mapping supplier workflow in ERPNext

Hello gays…
I want a little help

I use ERPNext 13.27.1 version.

I put a purchase order from a user account ( userone ), in here I set a another user ( usertwo ) as a supplier. Then I log into the my second user account ( usertwo ) , purchase order which I already created it is not visible inside my second user’s ( usertwo ) sales order section. what is the reason?

userone:
purchase user
purchase master manager
purchase master manager and customer roles are enable

usertwo:
sales user
sales master manager
sales master manager and supplier roles are enable
all document types for all user roles has 0 level permission ( sales order, sales invoice )

Thank you,
Buddhika S. Ranasinghe

You are trying to map 2 companies into 1. There is no automatic facility to create a sales order from a purchase order.

Thank you @rmehta

If is not facility. how can I do that ?
