Macro to hit Ok button or Enter command to an external application
SendKeys Onkeys are not working
Is there a way through vba I can hit OK or press enter in an external app?

Sub GetBOData()
Dim BOApp As Object
On Error Resume Next
Set BOApp = CreateObject("BusinessObjects.application")
With BOApp
.Visible = True
.LoginAs "aaaaa", "Xxxxx"

<Enter needs to be pressed here>

.Documents.Open ("C:\Users\abhpatil\Documents\My Business Objects Documents\userDocs\Test.rep")
With .ActiveDocument.Refresh
End With
End With
Set BOApp = Nothing
Set BODoc = Nothing
End Sub
