I want to allocate balance qty in sql.....

Question

Please help me…
I want to allocate balance qty in sql.....
I have data like below table and expected answer in column EDIT_UP_TO_EXEPECTED_ANS.
I want to edit data with validation of next process executed qty.
for example in row 3rd and 4th PROCESS_EXECUTE_QTY is ORDER_VRNO wise is 100 i.e.
100+0=100 and i want to allocated this qty in 1st and 2nd row i.e. 75,25 i.e. 75+25=100
because first process CUTTING of jobcard_no J113Y-1004 is 75 and next process done is 100 order_vrno wise
so i want to allocated 100 in 75,100 i.e. 75,25 total should be next process execute qty i.e. 100

Just a guess  ( with some data changed and an order column added)
with t as
(select 1 SLNO,'J113Y-1004' jobcard_no,'P113Y-56' ORDER_VRNO,'CUTTING' PROCESS_CODE,1 ord,75 PROCESS_EXECUTE_QTY,0 EDIT_UP_TO_EXEPECTED_ANS      FROM DUAL UNION ALL
select 2,'J113Y-1005','P113Y-56','CUTTING',1,100,0 FROM DUAL UNION ALL
select 1,'J113Y-1004','P113Y-56','DRILLING',2,85,0 FROM DUAL UNION ALL
select 2,'J113Y-1005','P113Y-56','DRILLING',2,0,0 FROM DUAL UNION ALL
select 1,'J113Y-1004','P113Y-56','PUNCHING',3,15,0 FROM DUAL UNION ALL
select 2,'J113Y-1005','P113Y-56','PUNCHING',3,0,0 FROM DUAL UNION ALL
select 1,'J113Y-1004','P113Y-56','FORMING',4,0,0 FROM DUAL UNION ALL
select 2,'J113Y-1005','P113Y-56','FORMING',4,0,0 FROM DUAL
