Hi all,
I need some help regarding conditional filtering. I tried to look for solutions but was not able to find any.
Basically, I need to filter based on a hierarchy key on column Year and Type. For example in this, A is higher than and F is higher than O. E.g. for 1234 in 2022 since both O and F exist, we just want F. However, in 12345 2023, only O exists so we will take O. X and Y are misc columns whose data should be kept. At the very end, only one row for each year should exist.
Any help is appreciated.
