Final answer:
There are several factors that could prevent data from appearing in a custom report, including too many metrics and dimensions, a filter that removes all data, and not sharing the custom report with relevant users.
Step-by-step explanation:
To prevent data from appearing in a custom report, there are a few possible reasons:
- Too many metrics: If there are too many metrics selected for the report, it can lead to a crowded report where the data may not be clearly visible or understandable.
- Too many dimensions: Similar to metrics, if there are too many dimensions selected for the report, it can result in a cluttered report that makes it difficult to interpret the data.
- A filter that removes all data: If a filter is applied to the custom report that removes all the data, then the report will appear empty or blank.
- Custom report isn't shared with users in the same view: If the custom report is not shared with users who have access to the same view, they will not be able to see the data in the report.
