Symptoms

Assume that you use the Invoke-AsCmd cmdlet in PowerShell and XML for Analysis (XMLA) in SQL Server Management Studio (SSMS) for Microsoft SQL Server 2012 Analysis Services (SSAS 2012) or SQL Server 2014 Analysis Services (SSAS 2014) processing. In this situation, you experience the following behavior difference for the returned output:

  • When you use the following PowerShell command to capture warning messages:Invoke-Ascmd -InputFile:"<input.xmla>" -Server:"<servername>" -OutVariable out -WarningVariable w If the command receives any warning message, the warning message is not captured in the return code. However, the warning message is captured if you run the same XMLA command from SSMS.

  • When you use the following PowerShell command to capture error messages:Invoke-Ascmd -InputFile: :"<input.xmla>" -Server:"<servername>" -ErrorVariable e -OutVariable out -WarningVariable w If the command receives any error message, the error message is included in the Warning tag but is not captured in the return code. However, the error message is included in the Error tag and is captured in the return code if you run the same XMLA command from SSMS.


Cause

This issue occurs because the Invoke-AsCmd cmdlet ignores warning messages but captures error messages, and it uses wrong templates to generate return output.
