VBA in BEx: macro call on saving a WB

Hi experts,

I want to know if it's possible to execute macros after clicking on standard button on BEx toolbar "Save an existing workbook"?

For example, the similar macro call for button "Refresh" we implemented as follows:

Sub SAPBEXonRefresh(queryID As String, resultArea As Range)

     Call plan_SAPBEXonRefresh(queryID, resultArea)

End Sub

But how can I do this for another button?

Hope for your help!

Thanks in advance,

     Mariya.
