Int Overflow

I have managed to avoid but not actually solve the issue.

The Case_Timeline table had columns in the database for number of days, hours and minutes and these were decimal values.  The columns were actually not required because Open and Close date and time are available so the duration can be caluclated in Power BI if I ever need it.  But since (at this time) I don't then I simply excluded those columns from the load and it worked fine.
