BAPI to change notification task completion date and time

Hi,

I am looking for a BAPI which will modifiy completion date and time of an existing task of a notification.

I was trying with BAPI_ALM_NOTIF_DATA_MODIFY but it doesn't have fields which can modify those fields.

Looking for your help. Can directly update QMSM table

should be a way?

Thanks,

Mainak
