So being in the legacy world for 20+ years and working with ancient
cobol/rpg code that a single pgm can span 10k+ lines of code, I still have
not found an efficient way to answer clients requests of "how is the data
arrived at in this table/column?" Aside from a whole lot of time, effort
and grunt work.

How do others handle these requests?

There is no shortcut, whether looking at a 20 year-old batch-based
system or a brand new system that was just deployed yesterday. As long
as the midrange market continues to treat documentation as the ugly wart
on the backside of software, brute force research is the only way to
extract business rules / knowledge from the code it is embedded within.
