Hi @Sarath_Nagesh,
First of all, I’m not familiar with Drools. Do you mean decision services?
Currently, the Camunda DMN engine doesn’t support decision services.
You need to compose the rules manually. Since you can call only one decision, this decision must call all dependent decisions (i.e. required decisions) and return all result values. For example, by using a decision table with one output for each result value, or by using a literal expression.
