Review, check Sales data tagged as Trunc Sales or transactions having CSANBR = 1 for the date range of Jan 2019 - Dec 2019.  Coordinate with JDA Team, Ms. Jane for checking and asked advice on what to do since there are sales that are already tagged as Trunc (CSANBR = 1) in 2019, even if the Trunc Server just only started Last Dec 2020. To confirm again tomorrow with Sir Rey on how we go about this issue.
