Datamart "OperationCanceled" error occurs randomly

[JK800]

Does anyone know a fix for this issue when a datamart is loading data? Microsoft Support as usual does not have a clue.

It has occured randomly across multiple datamart's in the same workspace for no apparent reason. Possible a correlation with changing an upstream dataflow, but not confirmed.

So far, we have had to re-build a datamart four to five times because this error seems unrecoverable.

Thank you!
