Hi,
| December 15, 2013 | Dec-2013 | Jan-2014 | |
| Demand | 39,904 | 38,150 | 16,974 |
| Supply | 27,962 | 42,027 | 32,390 |
| Projected Inventory | 25,401 | 29,278 | 44,694 |
Example: Projected Inventory for Dec-2013 = Prev Period Inventory + Current Period Supply - Current period demand = 25,401 + 42,027 - 38,150 = 29,278
How can i use the previous values of inventory to calculate the next on the fly in query designer 3.5
Thanks
GS
