Hello dear community,
I have a very big table with all financial movements, and if it's a movement between companys of the same group, I have a column named interco that marks the movement as "Company A - Company B".
When I select all movements from the column A, and column B less "Company A- Company B" I should obtain the ideal result, but due to some mismarked movements or other things, I have smalll diferences.
So my goal is to calculate the balance, and then the excess/defit in EBITDA should became the opposit or a cost or a revenue:
| Date | Cat | Value | Company | InterCom |
| 01/10/2023 | Sales | 10 | A | A-B |
| 01/10/2023 | Cost | -10 | B | A-B |
| 01/10/2023 | Sales | 5 | A | A-B |
As you can see, here you have an increase in sales, so If I select only company A or company B, I don't want to change anything but if I select the interco, I should add a row with the oposite signal e this case a cost in the company B.
I know it's quite confused but any suggestion is super apperciated
