Tracking code vs Last touch channel detail definition

[Monishasargunan]

Hlo community,

While getting the marketting channel campaign traffic data 

I can see the two dimension defining campaign name( last touch channel detail and tracking code) but data differs for both dimension

It sounds like you have two different dimensions, one called Tracking Code and the other part of the Marketing Channels functionality. These may count differently depending on your different set up for each.

It also sounds like you are not the person who set these up. You may want to find out who did the set up and what the respective configurations were used. That would better help you understand what the two numbers represent.

In general, tracking codes are used to track campaigns.  On the other hand, marketing channels/details are used to track all channels.

There are multiple reasons the values would not match.

Tracking codes are only overwritten by other campaign traffic.  For example, if a new visitor arrived via Email today, the last touch channel would be email.  The last touch detail and tracking code would both reflect the same tracking code.  Tomorrow, the visitor arrives via Organic Search.  The last touch channel and detail are updated based on the Organic Search, but the tracking code isn't overwritten.  (First touch channel/detail would remain based on email.)

In addition, both dimensions can be set to different persistence.  Marketing channel is also a rolling engagement window.  This means as long as the visitor is seen within the engagement window, channels will persist.  Tracking code, on the other hand, is set based on a certain number of days (not rolling).  It will expire after that period, or when replaced by another tracking code.
