When users click Post, the data doesn’t get updated—i.e., the data reverts back to what it was before updating. However, the data in the fact table is updated.
This is a known issue with SSAS servers. The SSAS server sometimes goes 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, simply re-deploy the Application in the Modeler.
