    Hi Anonymous,

     

    I'm afraid we can't do that for now. But I found a workaround indeed. The measures in an Excel model can be imported into PBI Desktop. And we can use VBA to create measures fastly. The workaround is clear now. Please try the demo in the attachment. 

    1. Install the DAX studio from here.

    2. Connect to the SSAS tabular and run the query below.

    select [name], [expression] from $SYSTEM.TMSCHEMA_MEASURES

    3. Now, we get all the measure names and their details (part 5 in the image). Copy the details to a workbook in sheet1 starting from cell A1.

    4. Copy a few cells in a sheet and create a very simple data model in Excel.

    5. Open the Visual Basic window and paste the code below and run it.

    Public Sub add_measure()
    
    Dim Mdl As Model
    Dim tbl As ModelTable
    Dim nRows As Integer
    Dim i As Integer
    Dim measureName As String
    Dim measureContent As String
    
    Set Mdl = ActiveWorkbook.Model
    Set tbl = Mdl.ModelTables(1)
    
    nRows = Sheet1.UsedRange.Rows.Count 'get the total rows
    For i = 1 To nRows
        measureName = Sheet1.Cells(i, 1)
        measureContent = Sheet1.Cells(i, 2)
        ' MsgBox measureName
        ' MsgBox measureContent
        Mdl.ModelMeasures.Add measureName, tbl, measureContent, Mdl.ModelFormatWholeNumber(1)  'insert a measure to the model
    Next i
    
    End Sub

    6. Now, we can see all the measures in the model and we can import all of them into Desktop.
