link between the Item and cProject and then cproject to PS Project

Dear Experts,

Could you please guide me on where I can find (in configuration) this connection, and what are the process steps to establish this connection:

1. Link between the Item and cProjec

2. cproject to PS Project

Is there any document created on that on SCN?

If not, kindly let me know the procedural steps for it.

Best Regards

Saurabh
