Update NETPR into CDPOS at the time of creation

Dear experts,

Is there any way to have value of NETPR of purchasing info record updated into table CDPOS at the time of creation? As I checked, system only update the table when NETPR is changed.

The story behind is that we are developing a report to display change history of NETPR in PIR using data from CDHDR & CDPOS, and the report must also display initial value of NETPR at the time of creation.

Thanks,

Duc.
