Symptom
Users select Update in an app, but the data reverts to what it was before updating.
Resolution
The data in the fact table is actually updated, but there's an issue with your SSAS server. SSAS servers sometimes go into idle mode and cannot respond to changes on the SQL server. This problem occurs on Azure machines, or when the server wakes up from sleep mode.
To resolve the problem, deploy the application in the Modeler.
