The message provides specific details about the transformation rule that failed validation.
  Cause
  The error message typically arises due to one or more of the following reasons:
  
  
  Incorrect Transformation Rule: The transformation rule specified may contain syntax errors or logical inconsistencies that prevent it from being validated successfully.
  
  
  Data Type Mismatch: The source and target data types may not match, leading to validation failures when the system attempts to apply the transformation.
  
  
  Missing or Incorrect Mapping: The mapping between source and target fields may be incomplete or incorrect, causing the transformation to fail.
  
  
  RFC Connection Issues: The error message includes an RFC (Remote Function Call) reference, which may indicate that there are issues with the RFC connection to the target system or that the target system is not reachable.
  
  
  Configuration Issues: There may be configuration issues in the SLT setup or in the transformation rules that need to be addressed.
  
  
  Solution
  To resolve the error, you can take the following steps:
  
  
  Review Transformation Rules: Check the transformation rule specified in the error message (&1 and &2) for any syntax errors or logical issues. Ensure that the rule is correctly defined.
  
  
  Check Data Types: Verify that the data types of the source and target fields are compatible. If there are mismatches, adjust the transformation rule accordingly.
