Adding a new custom field in 'Account Changes' tab in CAA3 tcode !

Hi,

I have added a new custom field in the tcode CAA3 through enhancement of structure ZCI_FKKVKP and activated change history for that field. When I change the contents of this field then the change history can been seen via Extras->Field Changes.

But I can't see this change history under Extras->Account changes.

Can anybody please suggest what needs to be done?

Thanks,

Uday
