About the DsCalculated Column
The DsCalculated Column element discussed here is available in Logi Info v12.5 but has been deprecated in later Info versions; consult the Release Notes for specific details.
The DsCalculated Column is similar to other elements designed to extend the data available in a datalayer. Like the DsAggregate Column element, it's added as a child element beneath DataLayer.Data Services and adds a new column to the data. This column value is derived data which is accessible using an @Data token.
The new column's value results from evaluating an expression, for each row in the datalayer. This calculated value is populated in the new column in every row of the data and can be used in further calculations, Summary Rows, Link Params, etc.
