  You attempt to assign a value to a field that is defined as a boolean type, but the value provided is not "true" or "false".

  Solution:
  To resolve this error, you should:
  
  Check the Field Definition: Verify the data type of the field you are trying to assign a value to. Ensure that it is indeed a boolean field.
  Assign Correct Values: Make sure that you are only assigning the values "true" or "false" (case-sensitive) to the boolean field. For example:
  DATA: lv_boolean TYPE abap_bool.
  lv_boolean = abap_true.  " Correct assignment
  lv_boolean = abap_false. " Correct assignment
  
  Review Code Logic: If the value is being derived from another variable or calculation, ensure that the logic correctly evaluates to a boolean value.
  
  Related Information:
