I walk through the process of extracting unique invoices from these systems, highlighting the challenges I faced with large data sets, including an error due to too many rows. I also explain how I summarize invoice data to compare sums between the two systems. I encourage viewers to download the two files for a better understanding of the data involved. Please take a moment to familiarize yourself with the unique customers and invoices as we move forward with this analysis.
