The data mart token in the myBMT system is a system-generated identifier designed to indicate which Power BI report has requested the data view. Since Power BI cannot send specific environmental identifiers (such as report titles or GUIDs) as part of its payload, this token acts as a substitute, providing a simple yet effective way to track requests.
When a data mart token is generated and registered within myBMT, it enables the system to identify the source of the data request. It’s crucial to use unique tokens for each report; reusing tokens can lead to misidentification and inaccuracies.
Key uses of the data mart token:
- Usage Statistics: Helps Data Engineering track which reports are accessing specific data views.
- Version Identification: Identifies which versions of data marts are in use, allowing Data Engineering to advise on updates or migration to more recent versions.
- Impact Assessment: Assists in assessing the impact of major updates or changes planned for a data view.
By ensuring tokens are uniquely assigned to each report, it supports better tracking, impact analysis, and proactive updates within the data ecosystem.
