Adobe over the years have had a number of different ways of tracking channels and modelling attribution.  This one I believe pre-dates marketing channels. There is no right or wrong answer as to when to use it (assuming you've got it set up correctly), it's just going to tell you something slightly ...

@Andrey_Osadchuk - that's a fair comment, I can't say these will be collected. Might be worth doing some testing if you are able to recreate the scenario.

Is the failed server call a link tracking call triggered on navigation from one screen to another? This is the only circumstance I've seen this "(failed)" status before. In this circumstance it doesn't necessarily mean that the server call has failed to reach Adobe i.e. data may still have been coll...

There can be a few different reasons for this (not all bad), what was the status against the failed server call?  (the successful one will have had a status of "200")

The segment as described will return any visits that contain "A then B within one page view" at any point within the journey.  So the journey described would be included as it matches this criteria. I also wondered whether turning off "count repeat instances" under the menu Project > Project Info & ...

Is it possible you have a conflicting Adobe Analytics processing rule which is overwriting the value with just the URL path?Can't think of any other way data would be affected between data warehouse and the reporting interface.

Yes, I think you've understood what I'm getting at.At the beginning of your original post you said you "work a lot with the previous page dimension"So I assume you've got access to both:a custom prop or an eVar which is capturing 'previous page'and the out of the box 'page' dimensionI'm suggesting b...

'Next page' in a table format:It sounds like you are capturing the 'previous page' into a prop or an eVar and using this as breakdown on 'page' to see what the previous page was.Conceptually you can just reverse these dimensions to get a 'next page' reporti.e. when you break 'previous page' down by ...

Apologies Urs, didn't mean to steal the credit!
