Dataflow Gen 1 refresh history missing

Hi PowerUp2000​,

I would try to separate “the refresh history UI is missing entries” from “the refreshes never actually started”.

Since the missing period is still recent, there are two places I would check before assuming the dataflows did not run.

First, Power BI exposes a Get Dataflow Transactions API for Gen1 dataflows:

GET /v1.0/myorg/groups/{groupId}/dataflows/{dataflowId}/transactions

I would check one of the affected dataflows there and see whether transactions exist for 29 July through 6 August even though they are absent from the refresh-history UI.

The second place is the Power BI activity log. Microsoft documents the RequestDataflowRefresh activity as being generated when a dataflow refresh starts, including scheduled refreshes. The activity log keeps up to four weeks of history, so that date range should still be available.

That gives you a useful distinction:

• transaction/activity exists, but refresh history is missing: likely a history/display/telemetry issue
• no transaction and no RequestDataflowRefresh activity: much stronger evidence that the scheduled refresh never started

The lack of failure emails does not necessarily prove the refresh succeeded, because if the scheduled refresh was never initiated there may not have been a failed refresh execution to notify you about.

I would also verify that the refresh schedule itself remained enabled throughout that period, just to rule out the schedule being disabled or altered during the incident.

If both the REST transactions and activity log are blank for the same week across multiple Gen1 dataflows, I would open a Microsoft Support case with a couple of affected dataflow IDs and that exact date range. That would be much stronger evidence than the missing UI history alone.
