Using Call keyword in a cell, example Call TableName 2. Using expression builder and calling appropriate function, example @(Pega-RULES:DecisionTable).ObtainValue(tools, StepPage, TableName) DecisionType UsingCall UsingExpression Decision Table Table Tree, Table Decision Tree Table, Tree, MapValue Table, Tree, MapValue MapValue MapValue MapValue, Tree, Table Hope this helps.
