• What is the cause and solution for SAP error message TT066 - Use EQ, NE, LT, LE, GT, GE or =, ><, <, <=, >, >= ?

  The SAP error message TT066 typically occurs when there is an issue with the comparison operators used in a selection screen or a query. This error indicates that the system expects a valid comparison operator but has encountered an invalid one. The message suggests using specific operators such as EQ (equal), NE (not equal), LT (less than), LE (less than or equal to), GT (greater than), GE (greater than or equal to), or their symbolic equivalents.
  Cause:
  
  Invalid Operator: The error is triggered when an invalid comparison operator is used in a selection condition or a query.
  Syntax Error: There may be a syntax error in the code where the comparison is being made.
  Data Type Mismatch: The data types of the fields being compared may not be compatible, leading to confusion in the operator's usage.
  
  Solution:
  
  Check Comparison Operators: Review the code or selection criteria to ensure that only valid operators (EQ, NE, LT, LE, GT, GE, =, ><, <, <=, >, >=) are being used.
  Correct Syntax: Ensure that the syntax of the statement is correct. For example, if you are using ABAP, make sure that the comparison is structured properly.
  Data Type Verification: Verify that the data types of the fields being compared are compatible. If necessary, convert the data types to ensure they match.
  Debugging: If the error persists, use debugging tools to trace the execution and identify where the invalid operator is being used.
