Set Change Pointer in SAP Banking Services

Hi Guru's,

I'm working on SAP Banking Services (BS),

i am analizing the communication with external system, distribute master data

from BS to BA (Sap Bank Analizer).

Normally if we made change to master data (MD) we are able to send

information to BA (standard generate a new version of MD).

The standard set the change pointers

for data changed and send a change message to BA. We want to do something with

a custom field added, so i am searching a mapping to add this custom field.

On our sistem are not configurated "standard" change pointers (BDCP2 BDCPD), but system use

a Change Notification Services.

anybody help?

thanks
