Hello,
I would appreciate your help for the below.
I am trying to do the calculation of (A+E-I) in column Group_2 based on Group_1 and Date columns. The output should give me the result of (A+E-I) for each date in Date column based on Group_1 e.g. for the date 01/2018 for 1 (in Group_2).
I Would appreciate if you can show me a way. Thanks a lot from now!
