What I typically do is build a string to hold everything. To make it easier,
I'll use something like:

Dim strOpenArgs As String

strOpenArgs = "heading=" & strHeading & ";" & _
"subheading=" & strSubHeading

DoCmd.OpenReport "NameOfReport", OpenArgs:=strOpenArgs

Then, in the Open event of the report, I parse that string:

Private Sub Report_Open(Cancel As Integer)

Dim lngLoop As Long
Dim strHeading As String
Dim strSubheading As String
Dim varArg As Variant
Dim varArgs As Variant

strHeading = "default value"
strSubheading = "default value"

If Len(Me.OpenArgs & vbNullString) 0 Then
' Break the OpenArgs argument into the various parameters
' by splitting on the semi-colons.
varArgs = Split(Me.OpenArgs, ";")
For lngLoop = LBound(varArgs) To UBound(varArgs)
' For each argument, split on the equal sign.
' The name of the argument will be varArg(0),
' the value of the argument will be varArg(1)
varArg = Split(varArgs(lngLoop), "=")
If UBound(varArg) 0 Then
Select Case LCase(varArg(0))
Case "heading"
strHeading = varArg(1)
Case "subheading"
strSubheading = varArg(1)
Case Else
MsgBox "You passed " & varArg(0) & vbCrLf & _
"Sorry: I don't know what to do with " & varArg(0) & "!"
End Select
End If
Next lngLoop
End If

' Check to see whether or not you have values for strHeading
' and strSubheading, and process accordingly.


End Sub

Got it. If I have 2 items to pass, say heading and subheading, is any
efficient way to do it?

Open the report along the lines of:

DoCmd.OpenReport "NameOfReport", OpenArgs:=Me.Name

Then, in the Open event of the report, check the value passed:

Private Sub Report_Open(Cancel As Integer)

Select Case Nz(Me.OpenArgs, vbNullString)
Case "NameOfForm1"
' do what you want if it was called from Form1
Case "NameOfForm2"
' do what you want if it was called from Form2
Case Else
' do you want to do anything if it was called from somewhere else?
End Select

End Sub
