ORA-01001: invalid cursor

   Hello Experts,

      I am trying to insert data into a table fetched  from a cursor variable for some reporting purposes. I am using the below procedure to insert the data into the table.

CREATE OR REPLACE PROCEDURE INSERT_TEMP
IS
RC <PackageName>.RETURN_CURSOR;
TYPE tabobj IS TABLE OF OBJ_INSERT%ROWTYPE;
tab tabobj;
BEGIN
FETCH RC BULK COLLECT INTO tab;
CLOSE RC;
FOR J IN 1..tab.COUNT LOOP
INSERT INTO OBJ_INSERT VALUES tab(J);
END LOOP;
END;

   SQL> BEGIN
