📚 Reference and Data

The Reference and Data section is the technical backbone of the CKB — a collection of cross-cutting reference articles that apply across every part of emax digital. Use it to look up KPI definitions, understand where data comes from, find out why figures may differ from Amazon's own reports, and learn how filtering and currency conversion work.

Data & Technical Reference

Data Sources Overview
The starting point for understanding what data feeds the platform. Covers the scope and update frequency of each connected source — Vendor Central, Seller Central, Amazon Advertising (SPA), Amazon DSP, AMC, and scraped data.

Data Lag and Refresh Schedules
Explains how long it takes for data to appear after connecting your account, the reporting granularities Amazon provides, and how emax digital extends historical data availability beyond Amazon's default look-back windows.

Data Quality and SLA
Why values shown in emax digital can differ from the Amazon UI, why year-to-date figures sometimes diverge, and what level of deviation is expected. Essential reading if a number doesn't match what you see in Vendor Central or Seller Central.

Filters & Display Settings

Filters — How Filtering Works Across the Tool
A complete reference for all filters available in emax digital — core filters (Marketplace, Reporting Period, Currency), catalogue filters (Tags, Auto Tag, Ad Eligibility), catalog view filters, and Chart Builder filters (Comparison Mode, Metrics, Date Range). Explains filter behaviour and interaction rules.

Auto-Tag Filter Reference
Explains how Auto-Tags work — system-generated tags that automatically categorise ASINs by attributes such as price tier or performance band. Available as a filter across Hub and Advertising dashboards.

Currency Conversion
How currency conversion works in emax digital — the ECB exchange rate source, conversion logic, and how to read multi-marketplace data that spans multiple currencies.
