The most efficient way to perform lookup in table
Hello guys, how are you? I'm having a very specific issue, and even knowing how to solve that in theory, I'm having serious performance problems, due to the obligatory use from a very heavy database - an azure cube developed by my company that provides data worldwide. I've come with an example in a fact table, where I have trips from loading vehicles with an initial weight in the beggining of the trip. I need to create a measurement (can't make new columns in the direct query) that calculates the initial weight for the next trip from this same vehicle. It's a very simple task with ALL filters and on, however the real table is not retrieving the data due to the mentioned size of the datamodel. I've been trying using the OFFSET funcion, but I'm not being able to make the logic work to my problem. Any suggestions? Below, the latest try I've made: Next trip weight = VAR vFrota = MAX('Shifts and Events'[VehicleUsedId]) VAR vData = MAX('Shifts and Events'[EventStartDateTime]) VAR vTab = FILTER( ALL('Shifts and Events'), 'Shifts and Events'[EventStartDateTime] > vData && 'Shifts and Events'[VehicleUsedId] = vFrota ) VAR vMenorData = CALCULATE( MIN('Shifts and Events'[EventStartDateTime]), vTab ) RETURN CALCULATE( MAX('Shifts and Events'[MeasureBeforeLoading(kg)]), FILTER( vTab, [EventStartDateTime] = vMenorData && [VehicleUsedId] = vFrota ) ) Below an example of how I'm trying to make the information appear: Thanks!
