Error in Bex Analyzer including the filter button command in Callback macro

Question

Hello,
I have the following problem with the function filter button in the Bex Analyzer included in the callback macro:
Because of using 2 hierarchies in the filter the setting drill down to level 2 in the query gives no right output in the Bex Analyzer. The drill down level 2 is not shown. SAP recommends the include of a filter button to solve this problem. With a filter button in the sheet the problem was solved.
But after including the filter button command in the callback macro I get an error in MS Excel.
The callback macro starts, the filter was set by the user and the data was refreshed. Because of the refreshing of the filter the callback function the callback function starts several times. After setting the filter the first time, the following macro avoids the several starting of the set filter function:
Sub CallBack(ParamArray varname())
On Error GoTo err_handler
   Dim lRange As Range
   Set lRange = varname(1)
'Filter entfernend/delete filter
Dim ZeichenFilter As Long
ZeichenFilter = Len(Sheet4.Cells(41, 3).Value)
Dim Filter1 As String, Filter2 As String
Filter1 = Left(Sheet4.Cells(28, 3), ZeichenFilter)
Filter2 = Left(Sheet4.Cells(41, 3).Value, ZeichenFilter)
If Filter1 <> Filter2 And Filter2 <> "" Then
    onAction = True
    onAction = False
End If
'Filter setzen mit einmaligem durchlaufen/set filter and run one time
If onAction = False Then
    onAction = True
    Call Sheet4.BUTTON_55_Click
    onAction = False
End If
exit_handler:
    Exit Sub
err_handler:
    MsgBox Err.Description, vbOKOnly, "Error in " & " setMusterSub"
    Resume exit_handler
End Sub
After the filter was set the callback macro starts the second time. Then the Bex Analyzer erros with the sandglass. The working on VBA is possible, but not the working with Bex Analyer . Values in Excel weren’t shown.
How can I avoid this error?

Once I am adding VAR_VALUE_1 to the static parameters, the system generates two messages error:
Program error in class SAPMSSY1 method : UNCAUGHT_EXCEPTION
System error in program SAPLRRS2 and form GET_SID-1
