May I seek support on a case where I have 2 columns
- 1st column is the incremental dates
- 2nd column is the aggregated sum of a size
I tried to use GROUP_Previous to generate a new column so I can find the exact size of a particular day but the operation failed.
Can I receive your advice on what transformation operation I can follow to get to the result we need.
the outcome we looking for is a new column that provides the exact StorageBytes for that particular report_date.
