Azure Cost Management Export

Question

Can you help me with the exports i want to configure the time of export in cost management so i can get all the data of yesterday because when i export it on automatic export for example i get the data of yesterday but only half not complete

Hello Noel Christopher Tee!

You’re not alone—many folks run into this frustration: you set up an automatic daily export from Azure Cost Management hoping to get a nice, complete file for “yesterday”… but the file is missing some data. Let’s break down why this happens and what you can (and can’t) do about it.

Why Is the Data Incomplete for “Yesterday”?

•	Azure processes and finalizes cost data throughout the day (in UTC time), and there’s often a lag for the last 24 hours. When your automatic export runs, the data for “yesterday” may not be fully finalized—so, the export is “month-to-date,” but the most recent day’s info is partial.

•	This isn’t due to a misconfiguration on your end—it’s simply how Microsoft batches and completes cost data in the backend. You might notice the latest data is always a little behind, especially if the export runs early in the day.

Can You Control the Export Timing?

•	You can set the export frequency (daily, monthly, one-time), but not the exact time of day the export executes. Microsoft controls when the automatic job runs, and it can shift due to internal Azure load balancing and processing.

•	Even if you try to schedule or trigger the export at a particular hour, the time may drift or revert, and there aren’t options in the portal to set a specific time for when the export should fire off each day.

•	Export schedules always use UTC time (not local time), but even with that, the exported data might still be a bit stale or missing the tail end of “yesterday.”

Practical Workarounds

•	**Wait a day to get full ** For reliable reporting, many teams configure their processes to always use the export from two days ago for “yesterday’s cost,” giving Azure enough time to finalize data and avoid partial exports.

•	Manual “on-demand” export: If you need perfectly up-to-date data, you can trigger an export manually a few hours after the day ends—but this isn’t practical for automation.

•	Monitor the export status: Sometimes, reviewing the export’s run history in the Azure portal can clue you in if a run was delayed or partial.

•	Use file overwrite: Enable the overwrite option if you want the latest file to replace the old one—a small help for keeping storage tidy, but it won’t force fresher data.

What You Should Expect

•	Don’t expect “yesterday”’s data to be final in today’s automatic export. Even Microsoft’s official docs and community forums point this out: there’s an unavoidable lag in cost calculation and exporting.

•	Plan dashboards and automations to work with data that may be one or even two days old to ensure your numbers are right.

Bottom Line

•	You can’t directly configure the exact timing of automatic cost exports, and getting complete “yesterday” data isn’t always possible. This is simply how Azure’s backend cost reporting system works at the moment.

•	For now, the best approach is patience—just pull in data that’s at least one day older than your current date when absolute finality is needed.

Let’s hope Microsoft improves this in the future, but for now, you’re doing everything right—it’s the system itself that takes a little time to catch up!
