Update Next Shift opeing balance with current shift closing balance

Question

hi,
 I have an aggregation table which have shiftwise, productwise, warehouse wise stock data. i want update the next shift opening balance with current  shift closing balance.
My table is
ID          ShiftDate         ShiftNumber   ProductID   OpeningBalance  Inward  Outward  ClosingBalance WarehouseID
1             2014-07-02         1                  1                  
0                   50           20                
30                1
2             2014-07-02          2                 1                  
50                   0              0                
50               1 
Actually my aggregation is already run and update the table like above. But after that user done a transaction and accounted in the first shift. So i need to reupdate the data after the accountshift. I update the outward and closing balance so the closing
balance of first shift is correct.
Now i want update opening balance of second shift needs to be updated based on the corresponding closing balance of the shift 1.
Please guide me for this. I can pass ShiftData and ShiftNumber as '2014-07-02' and 1 respectively.

Which is sql server version you'e using? If its sql 2012, you can use PARTITION BY with RANGE BETWEEN for this. 
Otherwise you need to use a correlated subquery logic using APPLY
