Cursor FOR UPDATE OF when querying multiple tables.

Question

When I run the below code I am able to update the required table:
DECLARE
    CURSOR cur_get_recs1 IS
        SELECT *
          FROM ncotestaging os
         WHERE os.ote_status = 1
           AND os.action_type = 'A'
           FOR UPDATE OF ote_status;
BEGIN
    FOR recOTEstage IN cur_get_recs2
    LOOP
       dbms_output.put_line('Updating Row from ' || recOTEstage.ote_status || ' to: 2');
        UPDATE ncotestaging
           SET ote_status = 2
         WHERE CURRENT OF cur_get_recs2;
    END LOOP;
END;
/Results as expected on my 5 rows...
SQL> @test.sql
Updating Row from 1 to: 2
Updating Row from 1 to: 2
Updating Row from 1 to: 2
Updating Row from 1 to: 2
Updating Row from 1 to: 2However, when I update the Cursor to the following....
    CURSOR cur_get_recs1 IS
        SELECT os.*, ces.customer_ref, ces.product_code
          FROM ncotestaging os,
                   custRefSource ces
         WHERE os.ote_status = 1
           AND os.action_type = 'A'
           AND ces.ref_source = os.service_code
           FOR UPDATE OF ncotestaging.ote_status;I get the following error...
SQL> @test.sql
           FOR UPDATE OF ncotestaging.ote_status;
ERROR at line 18:
ORA-06550: line 18, column 26:
PL/SQL: ORA-00904: "NCOTESTAGING"."OTE_STATUS": invalid identifier
ORA-06550: line 12, column 9:
PL/SQL: SQL Statement ignored
ORA-06550: line 25, column 54:
PLS-00364: loop index variable 'RECOTESTAGE' use is invalid
ORA-06550: line 25, column 9:
PL/SQL: Statement ignoredI don't know why the FOR UPDATE statement reports an invalid identifier. I seem to have the syntax correct according to the PL/SQL documentation. Any pointers gratefully received.
