Tcode/Procedure to distinguish material wrt procurment type.

Dear SAP Experts,

Pl tell me, suppose I have a plenty of FERT materials & in which some are In house produced ( Procurment Type-F) & some are Externally Procured (Procurment type-E).

Now suppose I don't know which are In house or Externally procured.

So is there any Tcode or procedure to display these materials which clearly distinguish these two types?

Your all answers are valuable to me.

Regards,

Mehul
