bapi_alm_notif_changeusrstat does not change data even after commit

Hello all

I'm calling bapi_alm_notif_changeusrstat from a function module I've built.

My function module is called during an update task.

The problem is that the bapi doesn't update the data it suppose to update.

If however I call my function module without specifing

"update task" the bapi work just fine.

The problem is I can't ommit the "update task"

Does anyone have an Idea ?
