Is it possible to create a scripted field that will calculate percentage variance at aggregate level?

For Example, the below data table is at detail level – the total variance that we are getting as 16 which is incorrect, instead it should be 6

Example 1  
The below data table is at detail level – the total that we are getting is incorrect

| Category | Quantity 2019 | Quantity 2018 | Variance | Percentage Variance |
| --- | --- | --- | --- | --- |
| 100A | 10 | 8 | 2 | 1.25 |
| 100A | 12 | 15 | 3 | 0.8 |
| 100A | 15 | 12 | 3 | 1.25 |
| 100A | 12 | 20 | 8 | 0.6 |
| Total 100A | 49 | 55 | 16 | 3.9 |

Example 2: We want it at aggregated level. The numbers below are correct.

| Category | Quantity 2019 | Quantity 2018 | Variance | Percentage Variance |
| --- | --- | --- | --- | --- |
| 100A | 49 | 55 | 6 | 0.89 |

Can anyone Please help me on this scenario?  
Thanks in Advance.

Hello,

Scripted fields only work in the context of a single document, so they would not be able to do calculation at aggregation level.

Hi Marius,

Thanks for your response.  
Is there someother way we can achieve this in kibana directly or it would be also fine i can do this in elasticsearch.

Thanks
