Change Pointer for object class KLASSE, Message type - WPDWGR

Hi People,

I am trying to trigger change pointer WPDWGR01 IDoc whenever an hierarchy is created or changed(CLWM, CLWN).

I am using objectclass KLASSE.

All config is done -

BD50 done

BD52 object - KLASSE table - KLAH fieldname - key

BD61 done.

Although, CDHDR and CDPOS is updated. Change pointer table is not getting updated. I have activated BDCP2.

Please see if someone have any idea or faced same issue as other IDocs are working fine.
