• What is the cause and solution for SAP error message 01840 - Only the option '=' or pattern is possible here. ?

  The SAP error message "01840 Only the option '=' or pattern is possible here" typically occurs in the context of ABAP programming, particularly when using the SELECT statement or when dealing with conditions in a WHERE clause. This error indicates that the system expects a specific type of comparison operator, but it has encountered something else.
  Cause:
  
  Incorrect Operator Usage: The error usually arises when an invalid operator is used in a condition. In ABAP, when filtering data in a SELECT statement or in a WHERE clause, only the equality operator (=) or pattern matching (LIKE) is allowed in certain contexts.
  Syntax Errors: There may be a syntax error in the code that leads to the misinterpretation of the condition.
  Data Type Mismatch: If the data types of the fields being compared are incompatible, it can lead to this error.
  
  Solution:
  
  
  Check the Condition: Review the WHERE clause or the condition in your SELECT statement. Ensure that you are using either the = operator or the LIKE operator for pattern matching.
  SELECT * FROM your_table WHERE your_field = 'value'.
  or
  SELECT * FROM your_table WHERE your_field LIKE 'pattern%'.
  
  
  Correct Syntax: Ensure that the syntax of your SQL statement is correct. Look for misplaced parentheses, commas, or other syntax issues.
  
  
  Data Type Verification: Verify that the data types of the fields being compared are compatible. If necessary, perform type conversions to ensure compatibility.
  
  
  Use of IN Operator: If you are trying to use the IN operator, ensure that it is used correctly. The IN operator can be used with a list of values but should not be mixed with other operators in the same condition.
