FKKBIX651
- BRFplus: result data object of the function is not of Boolean type ?The SAP error message FKKBIX651 indicates that there is an issue with a BRFplus (Business Rule Framework plus) function where the result data object is expected to be of Boolean type (true/false), but it is not. This error typically arises when the function is designed to return a Boolean value, but the actual data type of the result is different (e.g., it could be a string, integer, or another type).
Cause:
- Incorrect Data Type Definition: The result data object in the BRFplus function is defined with a data type that is not Boolean.
- Function Logic: The logic within the function may be returning a value that is not Boolean, such as a string or numeric value.
- Mapping Issues: If the function is being called from another context or application, there may be a mismatch in how the result is being interpreted or mapped.
Solution:
Check Data Object Definition:
- Go to the BRFplus workbench and locate the function that is causing the error.
- Verify the data type of the result data object. Ensure that it is set to Boolean.
Review Function Logic:
- Inspect the rules and expressions within the function to ensure that they are returning a Boolean value.
- If the logic is complex, consider adding explicit checks or conversions to ensure the output is Boolean.
Test the Function:
- After making changes, test the function in the BRFplus workbench to ensure it returns the expected Boolean result.
Check Calling Context:
- If the function is being called from another application or context, ensure that the calling code is expecting a Boolean result and is handling it correctly.
