Thank you all for your help, I have resolved this issue now. Turns there was an issue with roles like Employee, Internal Employee and Internal User. I also didn't need to make any changes to the Company Tree for this to work.
Below are the steps I took:
- Create a new user, or you can use an existing one if you prefer.
- Create a new test employee or use an existing one if you prefer.
- In the Users screen, I opened up my test user record, assigned the test employee as a linked entity, and then cleared the User Type field. In the roles tab, I unticked any Internal User, Internal Employee and Employee roles.
- I then provided the Administrator role to this user as a test, but you can apply any roles that provide access to the Purchase Orders screen.
- Save your changes, log in as your test user, open a new Purchase Order, and you should see the Owner field filled in automatically with the associated employee.
Kind regards,
Andrew
