• What is the cause and solution for SAP error message FDT_EXPRESSIONS078 - AND/OR expression &1 has to be migrated to BOOLEAN via FDT_DCONV_0016 ?

  The SAP error message FDT_EXPRESSIONS078 indicates that there is an issue with an expression in the context of the Flexible Data Transfer (FDT) framework. Specifically, the error message states that the expression needs to be migrated to a BOOLEAN type. This typically occurs when the expression is not compatible with the expected data type for the operation being performed.
  Cause:
  
  Data Type Mismatch: The expression you are using is likely not in the BOOLEAN format, which is required for the operation. This can happen if the expression is returning a different data type (e.g., STRING, INTEGER) instead of BOOLEAN.
  Legacy Expressions: If you are using older expressions or configurations that have not been updated to comply with the latest standards or requirements of the FDT framework, you may encounter this error.
  Incorrect Logic: The logic used in the expression may not be correctly formulated to yield a BOOLEAN result.
  
  Solution:
  
  Review the Expression: Check the expression that is causing the error. Ensure that it is designed to return a BOOLEAN value. This may involve modifying the logic or the operators used in the expression.
  Use BOOLEAN Functions: If applicable, use functions or operators that explicitly return BOOLEAN values. For example, comparisons (e.g., A > B, A = B) will return BOOLEAN results.
  Migration: If the expression is part of a legacy configuration, you may need to migrate it to the new BOOLEAN format. This can involve rewriting the expression to ensure it adheres to the current standards.
  Testing: After making changes, test the expression to ensure it behaves as expected and resolves the error.
