In sales return from sales invoice, User with (POS, Sales User, Employee) Permission can’t edit items like snapshot!
Hi,
You can give access to these roles via the Role Permissions Manager and give read and edit access. To know more abut the same, check this link: //docs.erpnext.com/docs/user/manual/en/setting-up/users-and-permissions/role-based-permissions
Hope this helps.
