Exporting Decision Table as DMN

I do not know of a way to import/export DMN directly. Did you try to export a decision table like a normal application export and check the included XML?

Agree with you!
Appian uses DMN concepts/structure to design decision tables but does not support exporting the actual DMN model file.

The exported package cannot be read by other DMN engines or tools. It's Appian-to-Appian only.

Thanks for the responses so far.

It's really a pity because the core promise of DMN is portability, transparency, and standardization of decision logic across platforms. The idea is that a DMN model written in one tool should be executable in another, thanks to its standardized XML format and use of FEEL.

So it appears Appian's limitation includes:
 - DMN implementation is not designed for portability.
 - It’s not compliant with full DMN XML export, so you can’t move your decision logic to another DMN engine like Camunda or Drools.
 - It’s tightly coupled with Appian’s object model and security framework.

Unfortunately this means if portability is important to you (as it is for us), it pushes you away from using Appian as a central business rules platform.
