Power Pivot Tables not Refreshing

Take this:

• Check Power Query Dependencies: If your data is being pulled in using Power Query, make sure there are no changes or issues in the queries that could be causing the refresh to hang.
• Review Relationships and Calculations: Complex relationships and calculated columns/measures can sometimes cause refresh issues. Check for any new relationships or complex calculations added recently.
• Remove and Re-add Data Source: Try removing the data source from your Power Pivot model and then re-adding it. This can help resolve issues related to corrupt connections.
• Check for Circular References: Ensure there are no circular references in your data model, as they can cause refresh issues.
• Increase Excel Memory Allocation: If you are working with large datasets, consider increasing the memory allocation for Excel. This can be done in the Power Pivot settings under "Advanced Options."
• Disable Automatic Calculation: Temporarily set Excel to manual calculation mode before refreshing Power Pivot. This can help isolate the issue if it's related to complex calculations:
  • Go to the "Formulas" tab.
  • Click on "Calculation Options."
  • Select "Manual."
• Clear Cache: Clear the cache for Power Pivot to ensure there are no residual data causing the issue:
  • Open the Power Pivot window.
  • Go to "File" > "Clear Cache."
• Check Event Viewer Logs: Look for any error messages or warnings in the Windows Event Viewer logs that might provide more insight into the issue.
• Update Excel and Add-ins: Ensure your Excel and any related add-ins are up to date. Updates can sometimes fix bugs that cause issues with Power Pivot.
• Try a Different Machine: If possible, try refreshing the Power Pivot model on a different machine to rule out any local issues.
