Hi all
what is the use of running-difference . how can i use running-difference in cognos
It shows the change in a value of a row from its previous row. Think of unemployment numbers: you have column for month and then another for # of unemployed. You would use the running-difference to show the change of month 2 from month 1.
| Month | Num of Unemployed | Change |
| January | 200,000 | * |
| February | 160,000 | -40,000 |
| March | 220,000 | 60,000 |
