DMN13 — Expressions in Input Entries

Input Entries are defined as unary tests and as such do not allow even simple expressions. The need to exit the decision table into other FEEL constructs for simple expressions such as “Dividend Income * 0.30” makes the overall logic less readable. There are currently several tools that support expressions in decision table cells and this feature is also on Jan and James’ wishlist. The latter wrote about in more detail (http://blog.luxmagi.com/2016/04/our-dmn-2-0-wish-list-i-decision-logic/) so I won’t repeat it except to quote “This is something we see a lot of demand for by business users of DMN ‘in the field’.”

Support expressions in DT input entries

This is already supported in DMN 1.2. A positive unary test can be an Expression.
