I have cursor fetching some values from remote db and i m trying to store values in local table (see code below) I can run the select query alone succefully but when i use it inside plsql it fails with error.

DECLARE
TYPE MY_CURSOR
IS
     REF
     CURSOR;
          THE_CURSOR MY_CURSOR;
          V_CT          NUMBER(18);
          V_PSN_ID      VARCHAR2(30);
          V_INTERNET_ID VARCHAR2(75);
     BEGIN
          V_CT                                                                           :=0;
          OPEN THE_CURSOR FOR SELECT PSN_ID, 'TEST' FROM TABLE_A@PRO1 WHERE TABLE_A.SEQ_A<=1000;
          LOOP
               FETCH THE_CURSOR INTO V_PSN_ID, V_INTERNET_ID;
          EXIT
     WHEN THE_CURSOR%NOTFOUND;
           INSERT INTO PSN_EMAIL_SENT_TO@local
                    (PSN_ID, LAST_UPDT_DT
                    ) VALUES
                    (V_PSN_ID, SYSDATE
                    );
          
          V_CT:=V_CT+1;
     END LOOP;
     CLOSE THE_CURSOR;
     DBMS_OUTPUT.PUT_LINE
     (
          TO_CHAR(V_CT)
     )
     ;
END;

*Cause:    An error has occurred when trying to look up a remote object.
*Action:   Fix the error.  Make sure the remote database system has run
           KGLR.SQL to create necessary views used for querying/looking up
           objects stored in the database.
