• What is the cause and solution for SAP error message BRF673 - The BRF can only manage elementary result types ?

  The SAP error message BRF673 indicates that the Business Rule Framework (BRF) is encountering an issue with the result types being used in a rule. Specifically, the message states that "The BRF can only manage elementary result types," which means that the framework is unable to process the result type defined in the rule because it is not an elementary type.
  Cause:
  
  Non-Elementary Result Type: The result type defined in the BRF rule is likely a complex type (e.g., a structure or table) rather than a simple or elementary type (e.g., string, integer, boolean).
  Incorrect Configuration: The rule may have been configured incorrectly, leading to the use of a non-supported result type.
  Data Type Mismatch: There may be a mismatch between the expected data type and the actual data type being used in the rule.
  
  Solution:
  
  Check Result Type: Review the result type defined in the BRF rule. Ensure that it is an elementary type. If it is a complex type, consider changing it to an appropriate elementary type.
  Modify Rule Configuration: If the rule is intended to return a complex type, you may need to redesign the rule or use a different approach to handle the complex data.
  Use a Wrapper: If you need to return complex data, consider using a wrapper or a different mechanism to handle the data outside of the BRF.
  Consult Documentation: Refer to the SAP documentation for BRF to understand the supported result types and how to configure them correctly.
  
  Related Information:
  
  Elementary Types: In the context of BRF, elementary types include basic data types like strings, integers, and booleans. These are the types that BRF can handle directly.
  BRF Configuration: Familiarize yourself with the BRF configuration settings and best practices to avoid similar issues in the future.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or updates regarding this error message.
  
  If the issue persists after following these steps, consider reaching out to SAP support or consulting with a technical expert familiar with BRF for further assistance.
