Hello @Ahmed ELHOULA ,
Welcome to the Microsoft Q&A platform.
You may experience this error message when you've reached the integration runtime's capacity limit.
Error message:
Type=Microsoft.DataTransfer.Execution.Core.ExecutionException,Message=There are substantial concurrent MappingDataflow executions which is causing failures due to throttling under Integration Runtime 'AutoResolveIntegrationRuntime'.
Cause: You've reached the integration runtime's capacity limit. You might be running a large amount of data flow by using the same integration runtime at the same time. See Azure subscription and service limits, quotas, and constraints for details.
Resolution:
- Run your pipelines at different trigger times.
- Create a new integration runtime, and split your pipelines across multiple integration runtimes.
Reference: A pipeline run fails when you reach the capacity limit of the integration runtime
Hope this helps. Do let us know if you any further queries.
