I use access to run a bunch of custom reports via odbc for a client of mine. the reports pull from G/L, A/P and Job cost. I want to bring them to v2015 or v2017, but I need to know first if the data file names, field names, etc. have changed? Thanks…

What are these fields? I have one on my check form (Check: Remarks (above name) Block) but I cannot figure what purpose it serves.
