Sample code for enhancement APOCFPRV

Hi,

Can any one provide me sample code for enhancement APOCFPRV to influence the publication of reservation data from SAP APO to SAP

R/3 using SAP APO Core Interface (CIF)?

I want to CIF dependent requirements to ECC from APO those are not available in ECC generated against planned order since the planned order are not in ECC. This is variant configuration scenario.

Thanks in advance.
