  The SAP error message RSDD_LM066 indicates that there is a mismatch in the operand types used in a calculation within a query or a data model in SAP BW (Business Warehouse). This error typically arises when the data types of the operands involved in a calculation do not match the expected types.
  Cause:
  
  Mismatched Data Types: The error occurs when the calculation is expecting a certain data type (e.g., numeric, string, date) but receives a different type. For example, if a calculation expects a numeric value but receives a string, this error will be triggered.
  Incorrect Query Design: The query or calculation might be incorrectly designed, leading to the use of incompatible data types.
  Data Source Issues: The underlying data source might have changed, leading to unexpected data types being used in the calculations.
  
  Solution:

  Modify the Calculation: If necessary, modify the calculation to ensure that all operands are compatible. This may involve converting data types or changing the logic of the calculation.
  Data Type Conversion: If you need to convert data types, you can use functions like CONVERT_TO_STRING, CONVERT_TO_NUMERIC, etc., depending on the required type.
  Review Query Design: Ensure that the query is designed correctly and that all fields used in calculations are appropriate for the intended operations.
  Test with Sample Data: If possible, test the calculation with sample data to ensure that it behaves as expected and does not produce type mismatches.
