Carry-Forward Functionaly in Conoslidation Package

Hi, BPC Experts:

I am using BPC 7.5 SP03. Now, When I am running Consolidation Package in 2011.Jan, part of the values in datasource with A Datasource Type in 2010.Dec are carry forward to the openging flow 2011 Jan. And after I delete the flow-type OPENING in opening flow member, all of the the values in datasource with A Datasource Type in 2010.Dec are carry forward to 2011 Jan. However, I don't want any of the values in datasource with A Datasource Type ilast year to be carry-forward to 2011 Jan Does anyone have similiar experience or advise for this issue? Thanks in advance.
