I recently updated the demand drivers in a specific model with a new demand file that had a different XLS name to the one previously used. I also replaced the Dem_Alloc+Series.xls. However, when I then tried to SYNC, I could not get rid of the old demand scenario file data, which remained in the VFE database.

The only solution seemed to be Start from scratch, which did of course remove the old data.

Is there a better approach to updating demand drivers, which does not require Start from scratch?

Thanks
