Difference between values in a single column based on an identifying value
Hi there community!
I'm working with a dataset in which I'm trying to display on Customer and Article level the sales Amount. This is done by looking at a set of seperate Excel files all with their own date of uploading (represented by File Date). These seperate files are combined in to one query by using the append queries function, and File Date functions as an identifying column to be able to differentiate between the seperate files that have been combined in to one query.
I have built a small dataset to give an idea on what kind of data I'm working with:
CustomerDelivery DateArticleAmountFile Date
| 1 | 23-10-2021 | 999 | 100 | 1-1-2022 |
| 1 | 12-12-2021 | 999 | 500 | 1-2-2022 |
| 1 | 30-12-2021 | 212 | 400 | 1-3-2022 |
| 1 | 15-1-2022 | 487 | 150 | 1-3-2022 |
| 1 | 18-3-2022 | 212 | 300 | 1-4-2022 |
| 2 | 12-12-2021 | 476 | 300 | 1-1-2022 |
| 2 | 23-5-2022 | 98 | 1000 | 1-2-2022 |
| 2 | 25-5-2022 | 146 | 20 | 1-2-2022 |
| 2 | 30-7-2022 | 999 | 500 | 1-3-2022 |
| 2 | 5-8-2022 | 358 | 700 | 1-5-2022 |
| 2 | 10-10-2022 | 487 | 100 | 1-4-2022 |
| 3 | 15-11-2021 | 564 | 500 | 1-1-2022 |
| 3 | 30-1-2022 | 999 | 400 | 1-3-2022 |
| 3 | 2-2-2022 | 154 | 50 | 1-3-2022 |
| 3 | 24-7-2022 | 308 | 800 | 1-5-2022 |
The data will be presented to the user in a matrix similar to the one below:
The user will be expanding this matrix to also get a detailed view on Article level, which would look something like this:
Using the matrices presented above I want to be able to compare values and show the differences. If Customer = 1 this would mean that the first matrix should also show the following values:
- +400 for the difference between 1-1-2022 and 1-2-2022
- +50 for the difference between 1-2-2022 and 1-3-2022
- -250 for the difference between 1-3-2022 and 1-4-2022
- -300 for the difference between 1-4-2022 and 1-5-2022
Ideally this difference is shown in percentages but to get it calculated in absolute numbers is a start. I have been struggling with this for a while now and I'm reaching out for suggestions as to how I can get a measure/column implemented to reach the desired result.
Looking forward to your suggestions and many thanks in advance!
Hi Anonymous ,
Please try:
% (Customer level) = var _nextDate= MINX(FILTER(ALL('Table'),[Customer]=MAX('Table'[Customer])&& [File Date]>MAX('Table'[File Date])),[File Date]) var _diff=CALCULATE(SUM('Table'[Amount]),FILTER(ALL('Table'), [Customer]=MAX('Table'[Customer]) &&[File Date]=_nextDate ))-SUM('Table'[Amount]) return DIVIDE(_diff,SUM('Table'[Amount]))Or
% (Article level) = var _nextDate= MINX(FILTER(ALL('Table'),[Customer]=MAX('Table'[Customer])&&[Article]=MAX('Table'[Article]) && [File Date]>MAX('Table'[File Date])),[File Date]) var _nextSum=CALCULATE(SUM('Table'[Amount]),FILTER(ALL('Table'), [Customer]=MAX('Table'[Customer])&&[Article]=MAX('Table'[Article])&&[File Date]=_nextDate )) var _current=CALCULATE(SUM('Table'[Amount]),FILTER('Table', [Customer]=MAX('Table'[Customer])&&[Article]=MAX('Table'[Article]))) return DIVIDE( _nextSum-_current, _current)Best Regards,
