Changetype Incorrect for ADCD?

[Flash]

Hi there,

I'm using TDI V7.1 and using the ADCD to populate a TAM repository.

I am getting variable behaviour with the changetype attribute which
the connector should be setting.

I am of the understanding that when ADCD detects a new key the
changetype should be "add", as in I need to "add" this object to the
destination. Ie,

2012-02-02 09:18:15,847 INFO [AssemblyLine.AssemblyLines/groupSync.1]

}'

Occasionally, I am getting a changetype of "modify". This does not
make sense to me.

In both cases, the Connector is reporting a new key. Is there any
specific behaviour which I am missing here which would cause the
change detector to set the changetype to modify?

There is some 'magic' going on in the AD CDC to differentiate new and
modified USNs (the keys that you have to use to figure out what has
changed in AD). It could be the component is not always successful. If
so, please raise a PMR with our support gurus and see if we can
tighten up the logic here.

Regardless, I assume you are using an Update mode Connector to write
to TAM (?), in which case this mode will handle add/modify for you.
And if you have 'add' specific logic then it can be applied in the
Before Add Hook (or Before Modify if it is 'modify' logic).

Hope this helps!
