Quick question about "BeginEdit()"

When we edit a template in SSMS, and import it to the SF, we get the following popup:
 

What does it mean? The SQL script seems to be imported correctly, and it can be executed so that it gets "active”. The arrow expands the following stack trace:

"   at System.Data.DataRow.GetDefaultRecord()
   at Thinkwise.Shared.ObjectModel.Obj.BuildMultipleRowsQuery(DataRow[] dataRows)
   at Thinkwise.Data.TSFController.refreshMultipleRowsCore(DataRow[] dataRows)
   at Thinkwise.Data.TSFController.refreshMultipleRowsAndUpdate(DataRow[] dataRows)"

Just curious about the implications of this.

Thanks,
