Updating custom field in BADI: CRM_MKT_MODIFY_ORDER method : MODIFY_ACTIVITY_OBJ

Hi Experts,

I have implemented BADI: CRM_MKT_MODIFY_ORDER - Method : MODIFY_ACTIVITY_OBJ which creates the activities for the BP’s assigned under the target group.

I have even added a new Z custom field through AET to the ORDERADM_H structure which I need to update while the Activities created in the BADI.

I cannot find the Z filed in the changing table

CT_HEADER TYPE CRMT_BUS2000110_HEADER_T

Can you suggest me how to update the custom field in the header ORDERADM_H

Thanks in advance.

Regards,

Chella.
