How do you add a "WC State, Code, Attribute" tab to PPOSE?

Hi Experts,

We want to start assigning WC state codes to positions in SAP. I noticed that you can do this using PO13, but I could not find a tab for it for position (S) in PPOSE. Is there a standard "Tab Page" that I should use when setting up a Scenario? The tab page descriptions are a bit vague.

Thanks for your help!

Regards,

Ryan
