Select sequences number in a Query

Question

I am facing problems while selecting the Sequence Number in a query.
create or replace view vfilemanifest as
(select abc.* , ts.* from (select filemanifestid.nextval from dual) abc ,
( select distinct batchid,custodianid from
tbatch tbat ,tcustodians tcstd, EXT_TAB_MASTERS ext_tab
where tbat.batchname = ext_tab.batchname
and tbat.batchpath = ext_tab.batchpath
and tcstd.custodianname = ext_tab.custodianname
and tcstd.custodianadd = ext_tab.custodianadd
)ts )
SQL> /
(select abc.* , ts.* from (select filemanifestid.nextval from dual) abc ,
ERROR at line 2:
ORA-02287: sequence number not allowed here
Please Advice

I'm sorry but that doesn't make it any clearer to me. This
using External Tables , View , Collection , bulk collect and Forall Insert is an implementation, not a business requirement. You might find some enlightenment in want to create a pl/sql table type dynamically I answered.
Anyway, I think what you want to do is this: (warning, untested code ahead!)
DECLARE
   TYPE lrec IS RECORD (
       id NUMBER,
       batchid tbatc.batchid%TYPE,
       custodianid tcustodians.custodianid%TYPE);
   TYPE ltab IS TABLE OF lrec;
   llist ltab;
BEGIN
   SELECT abc.* , ts.* BULK COLLECT INTO llist
   FROM  (select filemanifestid.nextval from dual) abc
         , ( select distinct batchid,custodianid
             from   tbatch tbat ,tcustodians tcstd, EXT_TAB_MASTERS ext_tab
             where tbat.batchname = ext_tab.batchname
             and tbat.batchpath = ext_tab.batchpath
             and tcstd.custodianname = ext_tab.custodianname
             and tcstd.custodianadd = ext_tab.custodianadd
           )ts 
END;
