Create custom reports

Before I publish this custom report for stakeholders, make it easy to scan. Put a short description of each metric at the top, show channel attribution rules used, make pricing and revenue columns clearly labeled, and add a quick filter for date ranges and device type. Flag any missing events that would make the report misleading.

I built the new custom report and it shows zero for several conversion events that we know fired. The product manager will assume the data pipeline is broken. I don’t know whether the event names changed, the view filters drop them, or permissions prevent me seeing them. What diagnostic steps should I run in order and how should I report the likely causes to the product manager?

Every time a stakeholder asks for a new report, I end up fixing event mappings, renaming channels, or reworking filters. It eats a day per request. What standard reporting foundation or three practices should I put in place so custom reports work first time and require minimal maintenance?
