Not too long ago I had a report generation request from an Alaska state agency. The request had some very specific requirements that detailed the use of user defined colors (by name), data driven control of the report, and Excel delivery using ODS and PROC REPORT. Along the way I had
Data access and data privacy are often fundamentally at odds with each other. Organizations want unfettered access to the data describing customers.
