I have a user profile that has fields from multiple sources. fields form AD and fields from BCS -> SQL DB. Everything is working, except if the DB is down, the fields get populated with empty data. However this is not the behavior I am looking for, I want to sync and if one of the sources is down, the current data is shown and not empty fields. I have been banging my head against the wall to this to work, in FIM and I can get one thing working or the other... it either updates or it does not update any changes if I disable Allow Null (from configure attribute flow).
How can I do this?
A Filter in the syncronization, some sort of rule? I am a bit lost
