SQL & PL/SQL :: FIFO Store Consumption

I need a query to divide the total consumption of an item into parts as it was stored in store on the basis of FIFO. The item that was stored first it will consumed first.

My sample data is given below.

DROP TABLE STORE_STOCK;
CREATE TABLE STORE_STOCK
(
no NUMBER(4),
vdate DATE,
code VARCHAR2(8),
clqty NUMBER(8,3),
dept_id NUMBER(4)
)
LOGGING
NOCOMPRESS
NOCACHE
NOPARALLEL
NOMONITORING;
[code]........

SQL>select * from store_stock
2 order by dept_id,vdate,no;

NO VDATE CODE CLQTY DEPT_ID
---------- --------- -------- ---------- ----------
359 21-JUL-12 012-042C 1050.1 19
2144 14-NOV-12 012-042C 990 19
1876 23-OCT-12 012-042C 1010 34
4006 12-MAR-13 012-043D 515.425 34
4086 15-MAR-13 012-043D 870 34
4495 13-APR-13 012-043D 498 34

6 rows selected.

SQL>select * from store_issue;

CODE IDATE DEPT_ID QTY
-------- --------- ---------- ----------
012-043D 24-APR-13 34 1650
012-042C 24-APR-13 19 990

Required Output will be

NO VDATE CODE CLQTY DEPT_ID ISS_QTY BAL_ISS
---------- --------- -------- ---------- ---------- ---------- ---------
359 21-JUL-12 012-042C 1050.1 19 990 0
2144 14-NOV-12 012-042C 990 19 0 0
1876 23-OCT-12 012-042C 1010 34 1010 640
4006 12-MAR-13 012-043D 515.425 34 515.425 124.575
4086 15-MAR-13 012-043D 870 34 124.575 0
4495 13-APR-13 012-043D 498 34 0 0

The total consumed against code '012-042C' is 990 for dept_id 19 and we have stored qty 1050.1 against goods receipt no 359 dated 12-jul-12. So have issued the whole qty against no 359 and balance is 0. For item code '012-043D' the total issuance is 1650 and we have issued it against 03 goods receipt nos.
