Hi guys,
I have a straight table where i need to find the difference between the values...
| Product Name | Month | sum([Actual Value]) |
| | | |
| AHU | Jan | 9368.44 |
| AHU | Feb | 8713.27 |
| AHU | Mar | 9637.76 |
| Chiller | Jan | 38690.87 |
| Chiller | Feb | 23797.2 |
| Chiller | Mar | 39456.88 |
| Elavator | Jan | 548.04 |
| Elavator | Feb | 487.34 |
| Elavator | Mar | 543.71 |
From above data i want to find difference between ( jan and feb) ie(8713.27 - 9368.44) values and then between(feb and mar) ie(9637.76 - 8713.27) values and so on...
what expression i need to write....
