HI, Power BI professionals~
I have +300,000 pieces of order information.
I am analyzing the savings compared to the unit amount of the previous month.
1. The left side is my data. Right side is the data want to create.
2. All data is generated additionally by the [EndPeriod]. => Flag : Add
- ex) the data of [Category = AAA & Index = 1] will only be checked for additional orders until [EndPeriod] = 202304.
3. [Dif.Amt] is the difference from the [AMT] in the previous index.
I'm waiting for your help.
Hello @DAMA_KIM
You can try duplicate left file , create new flag based on your condition, remove old flag and then append these 2 tables together.
