Can anybody tell me that;
1. Is primavera directly linked with Oracle Project Costing, Oracle Billing, Oracle Purchasing?
2. Also If I want to integrate Oracle Primavera with Oracle Projects then Oracle Project Management is mandetory or I can direclty integrate Primavera with Project Costing without using Oracle Project Management?
Thanks in advance.
By Oracle Primavera do you mean P6 EPPM or Contract Management?
In any case you have to develop your own integration solution using integration APIs, web services or Primavera Gateway. Alternatively you can use one of the Oracle Partners solution (https://solutions.oracle.com/scwar/sc/Partner/SC2PP-PROJECTP.html#solutions).
You do not need Oracle Project Management for the integration. You can integrate directly with Oracle Project Costing.
