Call decision table in when rule with parameter
Hello,
I want to use a decision table in which the first row is a parameter. This decision table should be evaluated in a when-rule, in which I pass the parameter to the decision table and get true or false back.
Is there a function which I can use to call a decision table with a parameter in a when-rule?
For Example:
|
Context (param.Function) |
Evaluation 1 | Evaluation 2 | Return | ||
|---|---|---|---|---|---|
| if | Function1 | true | true | ||
| else if | Function2 | true | true | ||
| otherwise |
false |
When-Rule: @FunctionToCallDecisionTableWithParameter("param.Function1", DecisionTableName)
Return-Value: True/False
If you have further questions, please let me know.

Found the easy solution.
1. Create Data Page D_ABC which takes the parameters as "Function".
2. Use Source as Data Transform and pass the Data page parameter to the Data transform.
3. Use @(Pega-RULES:DecisionTable).ObtainValue(tools, Primary, "DecisionTableName", true) function and set the result to data page . parameter from the data transform Param.Function will be automatically available inside the decision table.
example : Primary.Result = @(Pega-RULES:DecisionTable).ObtainValue(tools, Primary, "DecisionTableName", true)
4. use data page in When rule to evaluate the true/false. Pass any value to "Param.Function" as required in when rule
example: D_ABC[Function : "Param.Function"].Result == true
