The output row should look like this:
| Customer | Material | Quantity | Case | Date |
|---|---|---|---|---|
| ABC | XXX | 100 | 456 | 20130217 |
For what it's worth, I was able to get someone to write a SQL based Calculation view that works exactly like Lars has posted. However, once that was done I realized that in the data we have some materials with the last modified date/time that are identical down to the second. So now I'm going back to ask the SQL writer to use a second criteria in the SQL view for when there are still multiple records after pulling by minimum date.
