I work at a large bank and became aware of a policy that prohibits the use of excel in "production". I have built some larger worksheets with macros and this recently became a concern of our IT department. I am scheduled to meet with this area in the near future. I was wondering if there was anyone out there has heard of this kind of policy and what it specifically means. The worksheet in question is basically a large-scaled cash flow/forecasting tool. Thank you.
