ERPnext Manufacturing Module

Dear All,
I’m novice to ERPNext and was trying to implement BOM, Operation, Workstation etc. But Under Manufacturing I only have
Production
-> Production Order
-> Stock Entry
-> Timesheet
and
Bill of Materials
-> Item
I would want to setup “Workstation”, “Operation” etc, but not able to find where to… On the modules, I have all the modules ticked. Am I missing something.
Thanks,
Laxminarayan

Can you check the permission for those documents from Setup -> Role Permissions Manager?
