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.
Thanks, Marcel

Thanks PEDEL, got calrity on relationsship between When Rule and Decision Table.
Hi Vinod,
Can you explain how you implemented?
I want to pass a parameter , based on conditions within the table return true/false, and have that result be the result of a when rule. The reason why I want it indirectly from a when rule is because i want to call it from a proposition filter
as far as calling a decision table from when rule is concerned, you could use this -
Lib(Pega-RULES:DecisionTable).ObtainValue(this, myStepPage, "decisiontablename")
Note: The expression builder in when rule form doesn't return any results if you search with DecisonTable or ObtainValue. Weird!!
A When rule can call OOTB Decision Table obtainValue()
You are wanting a certain Parameter to be set in the step page's ParameterPage as opposed to using a Property within the step page itself?
There is not that much difference between the two - both are StringMaps.
Perhaps a PageGroup Property would meet your need?
You can set the PageGroup subscript dynamically using a Property value.
