    No you haven't, that's why you're getting this error. Most likely, your problem is with type mismatch. You are storing a char(8) in one table and a char(9) in another.

    Note: If you're really storing numbers, use NUMBER data type.

    Code:
    SQL> desc job
     Name                                      Null?    Type
     ----------------------------------------- -------- ----------------------------
     JOB_NUMBER                                NOT NULL CHAR(8)
     DATE_CREATED                                       DATE
     DEPT_ID                                            CHAR(9)
     POSITION_ID                                        CHAR(9)
    
    SQL> desc position

    notice position_id in job is 9 chars, in position is 8 chars.
