Hi Vinita,
If the attributes maintained for the user are not existing in HR system, then they should not be replicated by HR replication.
However would you please check if the attributes are inherited from upper organization?
If so, then maintenance in upper level will automatically affect this in user level.
If not, then the only possible reason is that somebody manually changed it, and you have to activate the change log for ppoma_bbp in order to trace this.
Best regards,
Ivy
