I am having some issues uploading the data file for this particular activity in Level 2 (126.96.36.199). i have provided screenshots below. I am getting an "invalid line item identifier: Volume" message. The data file that I downloaded has decimals going out to 8 decimal places (screenshot below). I formatted the number so that it goes out to 10 decimal places, but it is still not uploading. I also provided a screenshot of the mapping screen.
The mapping seems correct. Make sure you have created a number formatted line item 'Volumes' in your DAT03 Module. Map that line item to the 'Volume' column of your csv file from the 'DAT03 Historic Volumes Line Items' tab in your import action dialog box I hope it helps ~Anand
