Hi Frank,
For what I understand, it doesn't make any sense to add an excel step in this data move.
Is the data source of your datawindow a stored procedure ?
If yes, I won't call it an external datawindow.
If not, it should.
You will need an ODBC transaction for Access, something like that :
Transaction lt_Access lt_Access = CREATE Transaction lt_Access.DBMS = "ODBC" lt_Access.DBParm = "ConnectString='DRIVER={Microsoft Access Driver (*.mdb)};DBQ=C:\Data\MyDataBase.mdb',CommitOnDisconnect='No',DelimitIdentifier='No',PBNoCatalog='Yes',DisableBind=1"
I don't know pipelines but it seems to exactly fit your need, have a look at it (new>file>database>data pipeline)
Good luck.
Guillaume
