BRF254 - Details

• The SAP error message BRF254 ("No uniform result typing is possible") typically occurs in the context of Business Rule Framework (BRF+) when there is an inconsistency in the data types of the results being returned by a rule or decision table. This can happen when the rules are expected to return a single type of result, but the actual results vary in type.
  
  Cause:
  
  Inconsistent Data Types: The rules or expressions defined in the BRF+ application may return different data types (e.g., a mix of strings, integers, or other types) which cannot be unified into a single type.
  Decision Table Configuration: If a decision table is configured to return different types based on the conditions, it can lead to this error.
  Function Return Types: If a function is defined to return a specific type but the logic within the function leads to different types being returned, this can trigger the error.
