How to get a list of the rows that are executed in the collect policy of dmn.
Hello @teja_polisetty ,
as I understand your question, you want to map the result of a DMN table with a Collect Hit Policy to a BPMN process. That works like this:
This is the details panel of a Business Rule Task. As soon as you provide a result variable name, you will be able to select one of the result mappings. Collect will always provide a list. Depending on if you have one output column or many, you will either choose collectEntries or resultList.
Please ask your questions more precise in the future, as I had to guess what you meant.
Hope this helps.

oh no let me reframe my question
i am using collect policy with output as integer. so i am getting response of evaluate api call: as summation of all the outputs that satisifed …
Now if i go to cockpit and open that dmn instance : i can see what all rows got executed which resulted in final summation.
but how can i get these details in api : to check what all rows particiapted(executed) , which lead to that summation output result.
Hello @teja_polisetty ,
thank you for reframing the question, this helps a lot.
The data you are looking for should be stored in the history data of the engine.
For Rest API, please find the documentation here:
https://docs.camunda.org/manual/latest/reference/rest/history/decision-instance/
For Java API, I guess it will look quite similar.
Hope this helps

hi @jonathan.lukas
yeah in the database it is present and that’s why we are able to see the same in the cockpit right.
but I was looking to get this in the response of dmn evaluate(API call).
Is that possible?
thank you
Hello @teja_polisetty ,
the provided link will let you inspect the information you are looking for. An equivalent is also present in the engines’ HistoryService.
