  Check Return Values: Review the return values defined in your BRF+ rules or decision tables. Ensure that they are compatible with the aggregation type you are using.
  Adjust Aggregation Type: If the return values are correct but the aggregation type is not appropriate, consider changing the aggregation type to one that matches the return values.
  Data Type Validation: Ensure that the data types of the return values are consistent with the expected data types for the aggregation. For example, if you are using a numeric aggregation, ensure that the return values are numeric.
  Review Documentation: Consult the SAP documentation for BRF+ to understand the valid return values and aggregation types that can be used together.
