Hi coderHarder,
The field “Input Variable” with default “cellInput” is used differently than you describe in your question. The result of the “Expression” field is stored in “cellInput” (or under a different name if you specify it in the field “Input Variable”). You can then use “cellInput” (or the different name) in the expression in a input entry. Docs: DMN Decision Table Input | docs.camunda.org
I found a similar question here and adapted the provided solution to your question: DMN evaluate input List - #3 by hassang
In the “Expression” field we put “aktiveVertraege”. We leave the “Type” blank.
An input entry can then be written as:
list contains(cellInput, 30)
Checking with Postman:
Not containing 30:
Containing 30:
Unfortunately, the input entry is a bit more complex than a simple integer, but I hope it still suits your needs.
Kind regards
Till
