Help needed with combining data from BI Service using Dataflow Gen2

Hi ho86 - Might be the issue is with data connectivity, capacity limitations, or corrupted data models.

If you’re using Power BI Premium or Embedded capacity, this error may occur if the assigned capacity is either overloaded or has encountered an issue. You can monitor your capacity's health via the Capacity Metrics app in Power BI Service.

• Go to Settings > Admin Portal > Capacity settings and check whether your capacity is healthy or if it is under heavy load.
• If capacity is frequently maxing out, consider scaling up your capacity or optimizing the model.

If you are loading data from Dataflows (Gen2), double-check that the data has been successfully refreshed and the data model is intact.Test the connection by pulling the data into Power BI Desktop first. If the model loads successfully in Desktop, then the issue is more likely in Power BI Service.If it fails to load even in Power BI Desktop, the issue may be in the configuration of Dataflow Gen2 or the data model.Try optimizing the model by reducing the dataset size, removing unnecessary columns, or adjusting aggregation levels.

Use the Aggregations feature in Power BI to reduce the data model size for reports with very large datasets.
