JD Edwrads 9.2 Primavera Integration

Hello All ,

According to MOS note ID ID 2046566.1 , Oracle states that: “Product Portfolio Management Integration for Primavera 6 to JDE1. Use Primavera Gateway."

On the other hand Oracle JDE integrates with Primavera Contract Mgmt as described here : https://docs.oracle.com/cd/E64610_01/EOAIP/intro_to_prim_cm_integ.htm#EOAIP00032

Question : Primavera Contact Mgt integration with JDE covers all the basic needs of a construction company that uses both apps or Primavera Gateway is required to be engaged as well and on top ?

many Thx & Brgds
