Compatibility level for tabular models
APPLIES TO: SQL Server Analysis Services Azure Analysis Services Power BI Premium
The compatibility level refers to release-specific behaviors in the Analysis Services engine. For example, DirectQuery and tabular object metadata have different implementations depending on the compatibility level. In-general, you should choose the latest compatibility level supported by your servers.
The latest supported compatibility level is 1500
Major features in the 1500 compatibility level include:
Supported compatibility levels by version
|Compatibility level||Server version|
|1500||Azure Analysis Services, SQL Server 2019 (RC1 and later)|
|1400||Azure Analysis Services, SQL Server 2019, SQL Server 2017|
|1200||Azure Analysis Services, SQL Server 2019, SQL Server 2017, SQL Server 2016|
|1103||SQL Server 2017*, SQL Server 2016, SQL Server 2014, SQL Server 2012 SP1|
|1100||SQL Server 2017*, SQL Server 2016, SQL Server 2014, SQL Server 2012 SP1, SQL Server 2012|
* 1100 and 1103 compatibility levels are deprecated in SQL Server 2017.
Set compatibility level
Setting the 1500 compatibility level is not yet supported in SSDT.
When creating a new tabular model project in SQL Server Data Tools (SSDT), you can specify the compatibility level on the Tabular model designer dialog.
If you select the Do not show this message again option, all subsequent projects will use the compatibility level you specified as the default. You can change the default compatibility level in SSDT in Tools > Options.
To upgrade a tabular model project in SSDT, set the Compatibility Level property in the model Properties window. Keep in-mind, upgrading the compatibility level is irreversible.
Check compatibility level for a tabular database in SSMS
In SSMS, right-click the database name > Properties > Compatibility Level.
Check supported compatibility level for a server in SSMS
In SSMS, right-click the server name> Properties > Supported Compatibility Level.
This property specifies the highest compatibility level of a database that will run on the server. The supported compatibility level is read-only cannot be changed.
In SSMS, when connected to a SQL Server Analysis Services server, Azure Analysis Services server, or Power BI Premium workspace, the Supported Compatibility Level property will show 1200. This is a known issue and will be resolved in an upcoming SSMS update. When resolved, this property will show the highest supported compatibility level.
