If you need all the rows sum up if there is single Service Desk Ticket then try this way
LOAD * Inline
Service Desk Ticket, Time Reported
LOAD [Service Desk Ticket], sum([Time Reported]) as [Time Reported]
Resident T1 Group By [Service Desk Ticket];
DROP Table T1;
And in result you get the output as but question is what is the format of Time Reported here will it be minutes or what if values come in different format then you need to convert this field into minutes i guess.
