Level 2 - Sprint: Activity import Data into DAT03 Historic Volumes Module
I've been trying to inport the 'Historic volume.csv' to the DAT03 Historic Volume Module for the past 2 hours. I already watched all the videos about importing data to module, etc. But I keep receiving this error, "invalid line item identifier", and I don't know what else I can try. Could someone give me a hint?
Thanks in advance!
