Hey oodaddy2 - the mParticle Adobe integration leverages Adobe's data insertion API. mParticle maps their custom events to Adobe's track actions, their page views to Adobe track states, and their e-commerce API maps to Adobe's as well. Their docs lay things out in pretty good detail: https://docs.mparticle.com/integrations/amc/event/
Once your mParticle data is in Adobe, you can leverage processing rules to map the data into props, evars, etc. and begin populating your reports. The guide you seek is here: Processing Rules
