Synchro allows the import of a P6 schedule through an XML file exported from P6. The Synchro user importing the XML does NOT need to have P6 installed on their computer.
Alternatively you may import directly from the P6 database through the use of the Oracle Primavera P6 API. This is a free tool and works with both PPM and EPPM deployments of P6. With this method, the Synchro user must have P6 installed on the same computer or be able to log into P6 remotely (eg. through Loadspring)
The API, along with instructions to install and configure the API are available for download on our website at: www.synchroltd.com/downloads
Each version of P6 has its own API. Be sure to select the version of the API that matches your version of P6.
