A vendor needs an EIB that uses a custom report to output data for payroll...

Payroll results usually contain multiple related rows, so the report must identify the correct payroll result instance before outputting a single value. A True/False Condition is used to define which deduction rows qualify for evaluation, such as identifying valid deduction results. Extract Single Instance is then used to return one instance from that qualified set, typically based on a sort or selection rule that identifies the highest deduction. Evaluate Expression is unnecessary because the requirement is not an if/then output selection; it is selecting one related instance from a multi-instance group. Text Constant is also irrelevant because no fixed text value is being added to the output. This is a data transformation problem inside a report-driven EIB.
