Create and manage macros

I need a macro that standardizes the monthly closing file: it clears old notes, copies raw P&L into the standard template, runs the consolidation steps I do now (remove intercompany rows, apply FX rates from the Rates sheet, recalc subtotals), and saves a timestamped copy in the Closings folder. Make the macro ready for me to review before I assign it to the team.

Before I deploy this macro to the monthly closers, make it reviewer-friendly: add comments for each major block explaining assumptions, validate that intercompany rows exist and abort with a clear message if not, and log the filename and user who ran it to a hidden audit sheet so Kate can sign off without stepping through the code.

I ran an automation to clean up the monthly file and it removed three cost-center rows I needed. The team is upset and we can’t afford mistakes. I’m not sure whether the delete happened because of a bad lookup or because the macro used ActiveCell references. Given this, what is the fastest safe fix to restore trust and prevent recurrence before next close?

Our team has half a dozen macros doing overlapping tasks and nobody documents ownership. We waste time debugging and risk breaking things during close. What standard practices should we adopt for naming, code comments, versioning, and an approval checklist so macros become reliable assets instead of hazards?
