Looping through a list in Input Expression to evaluate decision

[Kiran_Balakrishna]

Hi All,

Is it possible to loop through a list in the Input Expression to evaluate decision for multiple entries in the list and return the results as a collection corresponding to the list?

Thanks,
Kiran B~

Hi @Kiran_Balakrishna,

evaluating a decision table for list of input values is not directly supported by the Camunda DMN engine. The easiest way to solve this issue is to use a BPMN process with a multi-instance business rule task. The multi-instance loops over the list of input values and the business rule task evaluates the decision table for every input.

Does this help you?
