Hi,
I have a dataset which is product data cross multiple years.
In some cases the same buyer bought the product in year 2022 and year 2021 and I want to roll this up into 1 line.
How do I do this automatically, matching on the word 'Buyer C' (because it's not feasible to manually match them with the size of the data)
Any help?
Also more explicit restrictions required than simply 'use Group By' or 'use string operations'
Thanks!
