SSMS connection error to Power BI analysis service on "Parameter already exists"

Dear Community,

I am trying to connect Power BI service dataset from SSMS, which was successful, however I can't process tables as it returns error message as follows : 

"

===================================

paramter name already exists
Parameter name: name (Microsoft.AnalysisServices.BackEnd)


------------------------------
Program Location:

at Microsoft.AnalysisServices.BackEnd.DataWarehouse.ConnectionStringBuilder.AddParameter(String name, String value)
at Microsoft.AnalysisServices.BackEnd.DataModelingUtility.AppendCatalogInfo(ConnectionStringBuilder connectionStringBuilder, String databaseName)
at Microsoft.AnalysisServices.ManagementDialogs.ImbiProcessDialog.DoPreProcessExecution(ExRunType runType, ExExecutionMode& executionResult)
at Microsoft.SqlServer.Management.SqlMgmt.SqlMgmtTreeViewControl.DoPreProcessExecutionAndRunViews(ExRunType runType)
at Microsoft.SqlServer.Management.SqlMgmt.SqlMgmtTreeViewControl.ExecuteForOlap(ExPreProcessExecutionInfo executionInfo, ExExecutionMode& executionResult)
at Microsoft.SqlServer.Management.SqlMgmt.SqlMgmtTreeViewControl.Microsoft.SqlServer.Management.SqlMgmt.IExExecutionAwareSqlControlCollection.PreProcessExecution(ExPreProcessExecutionInfo executionInfo, ExExecutionMode& executionResult)
at Microsoft.SqlServer.Management.SqlMgmt.ExExecutionAwareSqlControlWrapper.PreProcessExecution(PreProcessExecutionInfo executionInfo, ExecutionMode& executionResult)
at Microsoft.SqlServer.Management.SqlMgmt.ViewSwitcherControlsManager.RunNow(RunType runType, Object sender)

"

 

Please let me know if anyone knows how to resolve this.

 

Cheers,

Hi @VeraInSydney,

I suppose you are trying to provide duplicate parameters with the same name in the connection. please double-check your settings and connection to confirm these.

In addition, you can also take a look at the following link about a similar issue if helps:

"parameter name already exists" while trying to Process Database in SSMS (microsoft.com)
