Data Refresh Limitations in Power BI

Data refresh in Power BI
is subject to certain limitations, particularly in terms of frequency,
duration, and the number of refreshes allowed per day. These limitations can
vary depending on your Power BI licensing model. Here are some key
considerations:

1. Data Refresh Frequency:
• Power BI Pro users typically have a
  limit on the number of daily refreshes they can perform. By default, this
  limit is 8 refreshes per day for datasets in shared capacity, and 48
  refreshes per day for datasets in dedicated capacity (Premium).
• Power BI Premium users may have
  higher refresh frequency limits, depending on the capacity SKU.
2. Data Refresh Duration:
• Each data refresh operation is
  subject to a maximum duration, which can vary based on your licensing
  model and the underlying data source.
• Power BI Pro users may have shorter
  refresh durations compared to Premium users. For example, a single
  refresh operation might be limited to 30 minutes for Pro users, while
  Premium users may have longer refresh durations.
3. Concurrent Refreshes:
• Power BI limits the number of
  concurrent refresh operations that can be performed on a dataset. This
  limitation is more relevant in shared capacity environments where
  resources are shared among multiple users.
• Power BI Premium offers higher
  concurrency limits compared to Power BI Pro.
4. Scheduled Refresh:
• Scheduled refresh allows you to
  automate the refresh process at specific intervals (e.g., daily, weekly).
  The frequency of scheduled refreshes may be subject to the limitations
  mentioned above.
5. On-Demand Refresh:
• On-demand refresh allows users to
  manually trigger a refresh operation. The number of on-demand refreshes
  allowed per day may be subject to the same limitations as scheduled
  refreshes.
6. DirectQuery and Live Connections:
• DirectQuery and live connections to
  certain data sources may have additional limitations on data refresh,
  query complexity, and performance.
7. API Refresh:
• Power BI provides APIs for
  programmatically triggering data refresh operations. The frequency and
  limitations of API refresh may align with the constraints mentioned
  above.

It’s essential to review
the specific limitations and capabilities associated with your Power BI
licensing model and plan your data refresh strategy accordingly. Regular monitoring
of refresh operations and resource usage can help ensure that your datasets
remain up-to-date and accessible to users.
