Retrive change type of the members in a multi-value attribute in MIIS

Hi

This question raised in need on further elaboration to the post: http://social.technet.microsoft.com/Forums/en-US/identitylifecyclemanager/thread/2ec12b70-983e-473d-b16d-cc3ea40dfb70/


I have a call-based xma for export data to an oracle db.
In the export function now i have the problem that i can not determine the change-type of the members in a multi-value attribute. (add, delete or unchanged). So i don't know if i have to insert, delete or leave the members in the database.
How can i get the change-type of the members?

Part of the answer states:
"If you need to determine the individual change for each member [listed in a multi-valued attribute, red], you need to calculate this. The ECMA doesn't provide multi-valued attribute level changes."

Example:

CSEntry object

Name            (String)
Members      (Multi-value[String])

Multi-value table

CHANGE              VALUE
none                    Robert
none                    Kelly
add                      Jeremy
none                    Mandy
delete                  Johnny
none                    Brad

My question is, how do you retrieve the information in the collumn change? How am I to 'calculate' this?

Best Regards
