I'm trying to take data from two different sources, join them together, then with script transformation consolidate and average the data before exporting. So essentially, I have data that has date, duration, skill, and I want to consolidate it so that for each skill and date I have the average duration. I have vba code in Input0_ProcessInputRow that sums everything up but I do not know how to do the math out and assign to the output after this. Do I put it into the PostExecute()? If so, how do I create the rows for the output if the output fields are all different from the input.
