Yeah. It's a gompy product. I reproduced our old Remacs GL product in FM about 10 years ago and it's a beast. Just shy of 340 named cells with almost 200 of them using SQL snippets to populate. We have a few locations running multiple businesses off of one server. The "System" totals are actually RVC groups with a bunch of custom tables & stored procedures to define them and generate totals for each business, so making global changes across 19 locations without EM is just exhausting.
The upside is that FM gave me a way to pause the transfer of data from Micros to our accounting system, so our accountants can make their adjustments and dump the data right in to Great Plains without help from me. Which usually gives me time to move on to other headaches, like GSS, lol.
