About Decision Tables
Decision tables contain logic used to determine how a rule behaves. A rule may use a single decision table or multiple decision tables that work in concert. Decision tables can contain rule actions.
A decision table that contains a manual decision point (task action) needs to be configured in a particular way:
*The decision table must be process-aware. When creating the decision table, select the Process Aware check box.
*TaskData must be mapped.
*The task’s Inputs/Outputs must match the decision table’s Inputs/Outputs.
Note:  
The decision table contains an extra parameter called ProcessData that is automatically generated when the decision table is created. This is mapped separately to the process, not to the task.
*The decision table’s ProcessData must be mapped to the process.
Important:  
Do not overwrite or drop ProcessData as it contains necessary runtime data. ProcessData mappings must be only outgoing.
