Answer 1

You need to end your package body too -

CREATE OR REPLACE PACKAGE BODY EMP_DESIGNATION
AS
    PROCEDURE EMP_DETAILS(design employee.designation%TYPE, incentive number)
    IS
    BEGIN
        update employee set employee.salary = employee.salary + incentive where designation = design ;
        DBMS_OUTPUT.PUT_LINE(SQL%ROWCOUNT || ' employee(s) are updated');
         
    END;
END EMP_DESIGNATION;
