DMN: Output list of values

BPMN & Modeling Discussion & Questions

Is there any way to output a list of values (e.g. Strings) in the same column?

I’m trying to achieve something like the following:

But unfortunately I’m getting runtime errors. I know that a solution might be to repeat the same rules and using the “Collect” policy, but I want to avoid this since I will be having many rules and duplicating them would make it unreadable.

Thanks in advance.

Hi @nmanitaras,

You can design a DRD with two decisions.

  • A decision table in which output values are assigned as a single string with a special symbol used as a separator (# symbol is used as a separtor in below example)
