How to update Z fields of DB Table using Standard BAPI

Hi All,

I have developed a report which posts data to coep table using BAPI "BAPI_ACC_PRIMARY_COSTS_POST". The program is running fine. But yesterday i was told to add 2 new "Z" fields in COEP DB table for storing some dates. Now How can I update these Z fields Using the same BAPI?

Thanks In Advance.
