Polonez1 Kindly It's refresh your session and re-run the flow to ensure the successful completion of all processes and to maintain the integrity of your data.


Then, consider using a delete activity to remove old files based on their last modified step.
You can also delete the rows based on specific conditions by setting up the appropriate rule in the "Alter Row" transformation.

    There is nothing to refresh because there are no more stages left, only source and sink. I'm wondering how Azure can allow such a thing to be published when the source and sink are not connected? More precisely, publish was with all steps and correct validation, but nothing remained after opening because there was a source that could not be deleted, although no error was when publishing dataflow.
