Need information on Connect Direct in SAP

Hi All,

Need some inputs on Connect Direct. (I don not have any idea on this )

My client is asking for Integral Specification Interface for Cost centers and WBS Projects .

I explored it in Google, But did not get full information. My queries are as below...

1. Where i will get the ABAP program for sending / receiving the data via Connect Direct ?

2. My Functional Consultant showed PHP coding. But I didn't get anything over there . What I can expect from FC to resolve this issue ?

3. Where I can check this Integral Specification Interface in SAP ABAP / PHP coding ?

Please help on this as I am new to this Connect Direct topic .

Awaiting for your valuable responses.

Thanks in advance.

Regards,

-Chetan
