+# The column that is not in the table
+
+Every reporting team has a version of this request, and it always sounds like a five minute job: "can we have a region column? It is just the state, mapped. And a line value - quantity times price. We do not need it stored, we just need it on the screen."
+
+It is never a five minute job - so Data Controller now does the obvious thing instead. You write the expression, and the EDIT screen shows the column: computed on every read, never stored, marked `fx` and read-only, so nobody has to wonder whether it is locked or simply has nothing to edit.
+
+The part that took the thinking is that they filter like any other column. That needed a DATA step view rather than a data step, and the reasoning is worth reading: [Derived variables: computed columns you can filter on](/derived-variables/).
+
+Reference: [Derived Variables](https://docs.datacontroller.io/derived-variables/).
+
+If a table of yours has been waiting for "just one more column", we would love to [hear from you](/contact).
+
+<!--
+Feed teaser for the article at /derived-variables/. The article carries the
+engineering - why a computed column is not automatically filterable, the DATA
+step view, the configuration table, the limits - so this post links to it
+rather than repeating it.
+
+Image prompt (cover): a clean, modern illustration on a white background: a
+spreadsheet grid rendered in soft slate and light blue, with the leftmost four
+columns showing plain data and three further columns floating slightly to the
+right, detached from the table, tinted light blue and italicised, each marked
+with a small "fx" badge. A thin left border separates the floating block from
+the stored columns. No text other than the fx badges. Flat vector style, brand
+palette: slate #314351, light blue #d3e5f2, accent green #79a843 used sparingly
+as a single dot.

allan	2c7a3b8465	Merge pull request 'feed(derived-variables): a teaser that links to the article' (#28 ) from site/derived-variables-feed into main publish / Build-and-publish (push) Failing after 3m58s Details Reviewed-on: #28	2026-10-28 00:22:48 +00:00
dc	d37538264a	feed(derived-variables): the cover is framed for a card, and the next-release line goes The cover is the same capture as the article's grid still - 1024 CSS px at 2x, clipped to the rows - so the derived columns are legible on the feed card rather than a thumbnail of a mostly-empty page. It also stops promising the next release, which is about to be stale.	2026-10-28 00:15:57 +00:00
dc	3d2ec5869b	feed(derived-variables): the announcement, not a second article The feed post had grown to 800 words and retold everything the blog article already covers. Feed is for short announcements, so this is now 180 words: the request every reporting team makes, the computed-against-locked marking, one line on why a derived column can be filtered, then a link to the article and the docs. The inline screenshot goes with the detail, leaving the cover.	2026-10-28 00:03:22 +00:00
dc	bc27894b38	feed(derived-variables): a column that is not in the table, and why filtering needed a view A short, opinionated post for the feed: the request that always sounds like five minutes, the marking that says a column is computed rather than locked, and the DATA step view that makes a derived column filterable. Links to the docs page and to a discovery call. Screenshots are from a real SAS backend, so the grid shown is the shipped one - fx badge, tinted cells, and the edge that opens the computed block.	2026-10-27 23:53:13 +00:00
