<!-- Source LinkedIn post:
Your reporting tables keep needing derived columns - and until now, the answer was a SAS hook script.
Change a price, and the revenue column updates itself. Stamp the user who made the change, in the same row, automatically. And when an email address doesn't look like an email address - block it before it ever reaches production.
Data Controller v7.13 ships live formulas in the editor grid. Configure a column with a rule like = PRICE * VOLUME and the value is computed on entry, spreadsheet-style, using the full function library (IF, SUM, ROUND and friends). A HARDFORMULA locks the column; a SOFTFORMULA lets the user override when the business needs it.
It completes the story started in 7.12 with regex validation - HARDREGEX blocks invalid patterns outright, SOFTREGEX highlights them as a warning. Both are one row of config in MPE_VALIDATIONS. No code, no deployment.
There are also special runtime values - so an audit column can read "sasdemo changed from orig-2" without anyone typing it:
=IF( DC.ROW_STATUS ="U","unedited",
DC.USER_NAME &" changed from "& DC.ORIG_VALUE )
Full write-up with live screenshots (and how the rules flow from config table to grid):
