How to run from Powershell a VBA macro that does a SAPLogon

Question

I have an Excel that uses the Analysis for Office Add-In. It has a VBA macro that, among other things, does this:

ThisWorkbook.Application.Run("SAPLogon", "DS_1", "100", "myuser", "mypassword")

When I run the macro form Excel it works, but I'm trying to automate it with Powershell, and when I try to call it form there, I get this error:

Run-time error '1004':
Cannot run the macro 'SAPLogon'. The macro may not be available in this 
workbook or all macros may be disabled.

As it tends to get disabled sometimes, I tried enabling the "Analysis" add-in first like this in the same macro:

For ndx = 1 To Application.COMAddIns.Count
    If Application.COMAddIns(ndx).Description = "Analysis" Then
        Application.COMAddIns(ndx).Connect = True
        Exit For
    End If
Next

But it still doesn't work. Running other macros from the same Powershel does work. What am I missing?

Answer 1

Here's a sample of my PowerShell code in which I'm opening an Excel file, running the macro CreateChart and saving then closing the file again.

$excel = new-object -comobject excel.application
$workbook = $excel.workbooks.open("C:\Excel\Temp\File.xlsx")
$worksheet = $workbook.worksheets.item(1)
$excel.Run("CreateChart")
$workbook.save()
$workbook.close()
$excel.quit()

I'd recommend adjusting this sample according to your code and check whether your way of running the macro was wrong perhaps.
