Production order confirmation details [4.6 Release]

Hello,

I am creating a BDC program for "Automation for Production order confirmation" by recording COR6 transaction [4.6 Release].

To create order confirmation (COR6), the user has to fill the data which is available in transaction COR3 as below.

Could any one suggest table names/ function modules/ Class methods etc to fetch above details in R/3 4.6 release.

Thanks in advance.

Kind Regards,

Ramesh.
