I have a project that requires to summarize the data from List1 to List 2 every time there's a new data created in List1.
List1: Raw data
| TransactionDate | Branch | Amount |
| 10/16/2020 | Branch 1 | 500 |
| 10/17/2020 | Branch 1 | 400 |
| 10/17/2020 | Branch 2 | 600 |
| 10/17/2020 | Branch 2 | 400 |
List2: Summary from List1
| TransactionDate | Branch | Amount |
| 10/16/2020 | Branch 1 | 500 |
| 10/17/2020 | Branch 1 | 400 |
| 10/17/2020 | Branch 2 | 1000 |
I tried to read other related problem but other post are using 2 variable.
In my case, I need to consider 3 factor.
Thank you in advanced for those who are willing to help.
