Confirmation on Marketing Channel Classification: CJA vs. AA

@dhana2 I don't have CJA, so I can't speak much to it's behaviours... but what you specified sounds about right from what I have seen. I was helping someone a while ago, and I recall that derived fields were in fact used for CJA (I also recall that this also impacted some of the rules pertaining to "Internal" because there is no longer a way to determine the "first hit of the visit")

You are correct in your assumptions for derived fields. I think it to be easier and more dynamic as a whole. You also have the whole list of fields in your dataset to work with so if you are collecting something for first pave view you can filter down to that for marketing channel. Additionally once you define a derived field you can pull that into another derived field much like using a segment in another segment. The feature has a lot of possibilities.

hi @dhana2 - you're right CJA uses derived field to set marketing channels.  Those changes are retroactive.  Changes to AA marketing channel rules are not retroactive.

However, in most cases you'll likely be parsing the same values and scenarios.  I'm not sure I fully understand your mention of sensitive information in the URL.  If you're parsing CIDs to set campaign data in AA (for example channel_campaign_audience_etc...), you can do the same in CJA.  Another way to do it, in both AA & CJA, is to pass more of an ID CID2001a, CID2001b, etc..  Then use classification uploads (AA) or lookup table (CJA) to add the metadata.  This method keeps the URL shorter and don't potentially expose as much information.

I recently wrote a blog post on CJA marketing channels & best practices.  Here's a link if it's helpful.
