 ### Export schedule
 
-Scheduled exports get affected by the time and day of week of when you initially create the export. When you create a scheduled export, the export runs at the same frequency for each export that runs later. For example, for a daily export of month-to-date costs export set at a daily frequency, the export runs during once each UTC day. Similarly for a weekly export, the export runs every week on the same UTC day as it is scheduled. Individual export runs can occur at different times throughout the day. So, avoid taking a firm dependency on the exact time of the export runs. Run timing depends on the active load present in Azure during a given UTC day. When an export run begins, your data should be available within 4 hours.

 ## Access exported data from other systems
 
-One of the purposes of exporting your Cost Management data is to access the data from external systems. You might use a dashboard system or other financial system. Such systems vary widely so showing an example wouldn't be practical.  However, you can get started with accessing your data from your applications at [Introduction to Azure Storage](../../storage/common/storage-introduction.md).
