This error is often encountered in ABAP programs, selection screens, or when using transaction codes that involve filtering data.

  = (equals)
  <> (not equal)
  > (greater than)
  < (less than)

  Check the Selection Criteria: Review the selection criteria you are using in your report or query. Ensure that you are using valid operators as listed above.
  
  
  Correct the Operator: Replace the invalid operator (&) with a valid one. For example, if you intended to check for equality, use = instead.
  
  
  Review Custom Code: If this error occurs in a custom ABAP program, check the code for any dynamic selection criteria that may be incorrectly formed. Ensure that the operators are correctly defined.
  
  
  Test the Changes: After making the necessary corrections, re-run the report or transaction to verify that the error has been resolved.
