ORA-00904: "CHWAHKAH": invalid identifier

Error at Line: 3 Column: 9,739
ID column is a text column, you need to surround your list elements with quotation marks
' like so
'PLAN4808' as they are text.
Without quotations, SQL is interpreting them as some sort of identifier (as the error message states) for a database object (table, column name, function, et cetera) otherwise.
