  The SAP error message FDT_EXPRESSIONS161 indicates that there is an issue with the parameters used in an expression within the SAP system, specifically in the context of Field Data Management (FDT). The error message states that the parameter provided is not a valid AND/OR parameter and that an elementary data object is needed.
  Cause:
  This error typically occurs when:
  
  Invalid Data Type: The expression is expecting an elementary data object (like a single field or a simple data type) but is receiving a complex data type or an invalid reference.
  Incorrect Expression Syntax: The syntax used in the expression may not conform to the expected format, leading to confusion in interpreting AND/OR conditions.
  Missing or Incorrect Parameters: The parameters used in the expression may be missing or incorrectly defined, leading to the inability to evaluate the expression properly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Expression: Review the expression where the error occurred. Ensure that all parameters used in the AND/OR conditions are elementary data objects. This means they should be simple fields or values rather than complex structures or references.
  
  
  Validate Data Types: Ensure that the data types of the parameters being used in the expression are compatible with what is expected. If you are using a field that is not elementary, consider changing it to a suitable elementary field.
  
  
  Review Syntax: Make sure that the syntax of the expression is correct. Look for any typos or incorrect usage of operators (AND/OR).
  
  
  Test with Simple Expressions: If you are unsure about the validity of your expression, try simplifying it. Start with a basic expression that uses known valid parameters and gradually build it up to identify where the error occurs.
  
  
  Consult Documentation: Refer to SAP documentation or help resources related to Field Data Management and expressions to understand the expected formats and types.
  
  
  Debugging: If you have access to debugging tools, you can step through the code to see where the expression is being evaluated and what parameters are being passed.
