I was told that once rows from a source sheet make their way to the Data Mesh sheet, there is no way to remove them. Even though the rows may no longer exist in the source sheet, you can't prevent them from showing up again in the Data Mesh sheet. My source sheet (report) is pulling from multiple projects so it's not feasible to know what rows were deleted by project managers. I have no way of knowing what they deleted in their sheets feeding to the report, that then feeds to the Data Mesh sheet. Just want to be able to report accurately that rows in the Data Mesh sheet ARE active/live and not old rows that were deleted. Anyone have thoughts on this? Hopefully Smartsheet can develop a way to prevent this from happening in the future.
