Table for the Field PLPOD-PVZNR-Super Ordinate Node in Recipe

Could someone help me to know, from which table can I get the values of the super ordinate node - field - PLPOD-PVZNR-- which is entered while creating a recipe using TCODE - C201.

I have checked in Table PLPO, but it does not seem to exist there.

I have searched a lot but the solution is still eluding.

Thanks in advance.
