Exam DP-600 topic 1 question 139 discussion

Step 1: Group by CustomerID and calculate the max version date per customer ID This step groups the data by CustomerID and determines the maximum VersionDate for each customer. This identifies the latest record for each customer. Step 2: Expand the All Rows detail column This step expands the detail column, making all the data within each group accessible. This is necessary to access the other columns associated with the maximum VersionDate. Step 3: Filter the query where the version date value equals the max version date value This step filters the data, keeping only the rows where the VersionDate matches the maximum VersionDate calculated in Step 1. This ensures that only the latest record for each customer is retained. Step 4: Remove duplicates based on CustomerID This step removes any remaining duplicate rows based on CustomerID. Since we've already filtered for the latest record, this step ensures only one record per customer remains.
