HELP URGENT - Error Details-904 view code

Hi good morning Community 

I have a question about a read only field, Using a select I am putting two filters, the first points to a persistent field and the other to a read only field but I get this error when I try to synchronize my custom logical unit Error Details-904 view code

Example i try to put in a Read only field this

SELECT PERSON_ID FROM ANYTABLEEXAMPLE WHERE customer_id =:CF$_CF_CUSTOMER_ID (This one it’s a Persistant Field) and person_name =:CF$_CF_PERSON_NAME (This it’s a read only field)

Have these types of errors ever happened to you?
