Is there a way you can open up a report that is stored in one database from another?

I have three databases.

DB1: Holds data and reports
DB2: Is a transfer database which takes the data in DB1 and makes a back up of that database, transfers it to a master DB (DB3) and clears out all tables in DB1.
DB3: Holds all appended data

What im trying to do is when I transfer from DB1 to DB3 by using DB2 I would like for DB2 to call DB1's transfer report to indicate how many records by table were transfered to DB3. I have no tables or reports in DB2, just a transfer module that is executed on button click. I have everything working right execpt I'm not sure how I can open up the report in DB1 after I transfer in DB2. Any help would be great.

This is what I got so far:

Code:
Public Function Harvester()
    Dim dbsTo, dbsFrom As Database
    Dim rsHarvest, rsTo, rsFrom As DAO.Recordset
    Dim i, RecCount As Integer
    Dim PathName, DbName, TableName, Action As String
    Dim wrkDefault As Workspace
    
    On Error GoTo HarvestErrorHandler

    DoCmd.Hourglass (True)
    '-----------------------------------------
    'First, make a backup copy of the database
    '-----------------------------------------
    Action = "Backup" 'Used to show current step if error occurs
    'PathName = "D:\Backup\QC Backup"
    PathName = Application.CurrentProject.Path + "\Backup"
    If Len(Dir(PathName, vbDirectory)) < 1 Then
        MkDir (PathName)
    End If
    DbName = "\" + Format(Now) + ".MDB"
    DbName = Replace(DbName, "/", "_")
    DbName = Replace(DbName, ":", "_")
    DbName = PathName + DbName
    Set wrkDefault = DBEngine.Workspaces(0)
    Set dbsTo = wrkDefault.CreateDatabase(DbName, dbLangGeneral)
    'Set dbsFrom = CurrentDb
    Set dbsFrom = DBEngine.OpenDatabase("C:\FBCB2_LUT.MDB")
    Set rsHarvest = dbsFrom.OpenRecordset("HARVEST")
    Do While Not rsHarvest.EOF()
        TableName = rsHarvest.Fields("TABLE")
        DoCmd.CopyObject DbName, TableName, acTable, TableName
        rsHarvest.MoveNext
    Loop
    dbsTo.Close
    
    '------------------------------------
    'Second, copy tables to harvest drive
    '------------------------------------
    Action = "Harvest"
    Set dbsTo = DBEngine.OpenDatabase("C:\Master.MDB")
    rsHarvest.MoveFirst
    Do While Not rsHarvest.EOF()
        TableName = rsHarvest.Fields("TABLE")
        Set rsFrom = dbsFrom.OpenRecordset(TableName)
        Set rsTo = dbsTo.OpenRecordset(TableName)
        RecCount = 0
        Do While Not rsFrom.EOF()
           RecCount = RecCount + 1
            rsTo.AddNew
            For i = 0 To rsFrom.Fields.Count - 1
                If rsTo.Fields(i).NAME <> rsFrom.Fields(i).NAME Then
                    MsgBox "Error: " + TableName + " Fields not the same"
                    GoTo Harvester_Exit
                End If
                rsTo.Fields(i) = rsFrom.Fields(i)
            Next
            rsTo.Update
            rsFrom.MoveNext
        Loop
        rsTo.Close
        rsFrom.Close
        
        rsHarvest.Edit
        rsHarvest.Fields("RecCount") = RecCount
        rsHarvest.Update
        rsHarvest.MoveNext
    Loop
    
    '-----------------------------------------------
    'Last, If no error yet then clear out the tables
    '-----------------------------------------------
    Action = "Clear"
    rsHarvest.MoveFirst
    Do While Not rsHarvest.EOF()
        TableName = rsHarvest.Fields("TABLE")
        Set rsFrom = dbsFrom.OpenRecordset(TableName)
        Do While Not rsFrom.EOF()
           rsFrom.MoveNext
        Loop
        rsFrom.Close
        rsHarvest.MoveNext
    Loop
    rsHarvest.Close
    dbsFrom.Close
    
    MsgBox "Harvest complete"
    Action = "Report"

   'This is where i'm stuck.  Here is where I want to open up the report that is in DB1.  The way I have it here it opens up the report if I had one in DB2.  How can I go about calling the report in DB1 at this step?

DoCmd.OpenReport ("Rpt_Transfer_Summary")
Harvester_Exit:
    DoCmd.Hourglass (False)
    Exit Function
    
HarvestErrorHandler:
        MsgBox "Error: " + Err.Description + _
        CStr(Err.Number) + " Table: " + TableName + _
        " Action: " + Action
        GoTo Harvester_Exit
End Functio
